In the absence of a true standard for browser extensions, maintaining compatibility with Chrome is important for Firefox developers and users.

About as close as Mozilla can come to outright saying, "Chrome is big enough and we're small enough that what they do _is_ the standard."

Still, it's encouraging to see that they're not removing the blocking API for now. I kind of hope this does push a few adblocker extensions to abandon Chrome.

zzzcpan• 7 years ago

I find it rather discouraging to hear they are not removing the blocking API for now. It's basically an empty statement, not reassurance. They still may or may not remove the API, they don't want to promise anything or show any commitment to users' needs and priorities.

wtallis2• 7 years ago

It's basically the same as what happened two months ago with Firefox for Android being EOL'd pending a major re-write that may or may not support extensions. Mozilla is not willing to publicly commit to keeping their key features alive, and they keep hinting at the possibility that they will be leaving users behind in an attempt to be more like Chrome.

Ygg23• 7 years ago

adblocker extensions to abandon Chrome.

Ha. As if that will ever happen. They'll probably just pivot to something else.

The reason Chrome can try to ditch ad blockers is that they are big enough, that your only choice is Chrome or GTFO.

Iolaum• 7 years ago

Your choice can well be firefox and chrome as a fallback when a website doesn't work and you care enough to bother opening chrome for it. Chrome has already ditched adblockers on mobile, firefox with adblockers and reader mode is a MUCH better mobile web experience.

Endy2• 7 years ago

What they should be saying is, "No, what Google is doing is Wrong with a capital WRONG and we're not going to accept their wishes in closing off what's left of the open Web."

But then they'd have to give up all their Google funding. And they're way too cowardly and corporate to do that.

tomComb2• 7 years ago

"closing off what's left of the open Web."

Seems a little over the top to me!

Also, Mozilla is very good at standing up to Google. They beat them on webasm, rust is arguably supplanting go, and most of all, it was Mozilla that effectively killed web components which were very dear to Google.

ocdtrekkie2• 7 years ago

This points to the disturbing truth of how incredibly complete Google's monopoly is: Even browsers not based on Chrome are strongly pushed to implement Chrome's platform changes anyways.

badsectoracula• 7 years ago

Mozilla abandoning their much more powerful XUL-based extension system for Chrome's inferior WebExtensions wasn't already an indicator towards that?

Ygg23• 7 years ago

more powerful XUL-based

At the time of conception, it was pretty great. However, that much customizability came at two expenses.

1) Web devs can't use XUL, because it's its own little cosmos, you as Web dev couldn't mod Firefox UI

2) The XUL was legacy software and super hard to optimize.

sp332• 7 years ago

Firefox is faster and more secure now that they don't have to maintain compatibility with a bunch of old extensions that touch a bunch of internal stuff. Firefox's WebExtension API goes well beyond Chrome's at this point and is still adding features.

cptskippy2• 7 years ago

Stop conflating unrelated matters.

Mozilla's decision to remove XUL Extension support was directly a result of their decision to replace XUL in favor of HTML5 as the UI design language of choice.

jcranmer• 7 years ago

It's been known since around 2010 or 2011 that the full extension system was too powerful for effective maintenance of Gecko. Going through XPCOM for everything prevents effective optimization within the codebase, and generally ensures that the APIs have to become less ergonomic compared to modern C++ (or JS, for that matter). Furthermore, multiprocess content tabs was heavily delayed because turning it on would break practically every extension (since you could no longer have synchronous access to content).

Moving away from that was definitely the right approach for Mozilla, but the timetable and effort into bringing up a non-XUL/XPCOM-based extension mechanism definitely left something to be desired.

chrisseaton• 7 years ago

Safari doesn't feel the pressure to implement this API - why does Firefox?

muddi900• 7 years ago

This is disappointing. Mozilla can't seem to make up their mind if they want to offer a different product from google or just "Chrome, but for nerds"

sorenjan• 7 years ago

Cross-origin communication: In Manifest v3, content scripts will have the same permissions as the page they are injected in. We are planning to implement this change.

What will this mean for GM.xmlHttpRequest in userscripts? Adding content from several different sites with userscripts can be very powerful.

input_sh• 7 years ago

Stylus (Stylish without the tracking) sure is a nice interface, but you don't really need an add-on for that functionality. Create "chrome/userContent.css" within your Firefox profile directory and populate it with something like:

    @-moz-document domain(example.com) {
        img { opacity: 0.05 !important; }
    }

Note that there's some about:config flag that needs to be switched since the version that got released today.

xg15• 7 years ago

Was wondering about that too - but this seems to be just a Spectre defense, not a change in what extensions can do.

The change[1] only affects content scripts because they run in the same process as the website. You're still able to fetch arbitrary origins in a background page. So GM has to move the fetch to the background page, then send the content to the script via message passing.

WhatIsDukkha2• 7 years ago

The tone of this post concerns me.

What comes across is that Google is not collaborating with Mozilla over the Manifest v3 changes.

Instead of using and appreciating the engaged Firefox developer ecosystem we have PM conference rooms in Google mandating huge changes based on... well they've been shady so far about their choices on Manifest v3.

The other thing that keeps bugging me about this is -

We need a tiered App store for browsers. Part of the lockdown Google wants to do isn't wrong but its driven by having WAY too many bad actors and shoddy developers in their Chrome store.

If you have an opensource web extension, a reasonable community and with reproducible builds? You can use more powerful API versions.

If you are jrando bizplan #2000283 you get the kinda trusted tier.

Frankly if Debian had a web browser extension "store" with 20 things in it, I'd use that exclusively and turn off both the Chrome and the Firefox store 100%.

derefr2• 7 years ago

a tiered App store

We kinda have one; the tiers are "the public app store" and "your enterprise's private collection of apps, whitelisted by GSuite policy on your GSuite users."

Things are in equilibrium because no big player is complaining; and no big players are complaining because they have all their needs met by just 1. getting custom extension builds from vendors, 2. signing them with their enterprise cert, 3. pushing them to some object store, and 4. telling GSuite to allow them (https://docs.google.com/document/d/1pT0ZSbGdrbGvuCsVD2jjxrw-...).

beacker• 7 years ago

There are a handful of extensions for Firefox and Chrome in the Debian repositories: https://packages.debian.org/search?keywords=webext-&searchon...

xvector• 7 years ago

I'd like one of the PMs at Google working on this feature to engage in actual community discussion around this issue.

Google is not a monolithic corporation. Individual people are responsible for these decisions. These people are obligated to discuss why they are making these changes, else they deserve to be called out if they refuse to do so.

Is it too much to ask for these PMs to take some personal responsibility and engage in discussion for the far-reaching changes they are forcing upon society?

aledalgrande• 7 years ago

I don't think Google would have published a public note about their plans if there hadn't been a previous discussion.

masklinn• 7 years ago

What comes across is that Google is not collaborating with Mozilla over the Manifest v3 changes.

Well… duh? Google will do whatever it wants with no regards to anyone else unless they're forced to do otherwise, and "the market" will not force them to do otherwise unless their very large browser majority falls. From the moment mozilla decided (/ was forced) to adopt chrome extensions they were bound to follow google's whims.

mikekchar• 7 years ago

Having done a fairly long stint in the telephony world, I can say that the general purpose of standards committees is to rush through a whole bunch of hacky changes on your platform and then strong arm everyone else to implement what you did -- the more work they have to do the better; the worse it fits into their original ecosystem the better. Your goal is to make your competition perpetually play catch up and to have a slightly wonkier version of your system.

People in large organisations take this stuff very seriously and it can be difficult for other people to concentrate on making a good spec that will work well for everybody. The idea is that the market is pretty much the same size whether you have a fantastic application or a hacked together application. What matters for the company is what percentage of the market share you have. It's worth a considerable amount of fit-for-purpose in order to lock in eternal advantage over your competition.

purple_ducks2• 7 years ago

Chrome's June 2019 statement about Manifest v3 in which they tell us all how much they really care about users and this totes isn't to weaken ad blocking(which directly affects their revenue - that's just a coincidence - pinky promise!):

https://blog.chromium.org/2019/06/web-request-and-declarativ...

Ajedi32• 7 years ago

Here's an interesting thought experiment: what would it take to convince you that this change really is being made for performance and security reasons, and not to hurt ad blocking?

Given the level of cynicism directed at Google by the HN community, is it even possible for Chrome to lock down extension permissions in a way which wouldn't be seen as some sort of aggressive move against ad blocking? Keep in mind that secure, user-friendly permissions systems do have to be somewhat restrictive in order to be effective (see Android, iOS, etc), and that ad blocking extensions will necessarily be impacted as a result.

purple_ducks2• 7 years ago

Maybe make this step after discussing & listening to the other browser makers who support extensions.

Maybe listen to the people who actually write the ad blockers.

"I think they've been trying to give the impression that they’re working with the developer community, when in fact they’re pretty entrenched in what they want to do," says Jeremy Tillman, president of the privacy and security-focused ad blocker Ghostery."

https://www.wired.com/story/google-chrome-ad-blockers-extens...

michaelmrose3• 7 years ago

It doesn't lock down the ability of extensions to inspect and spy on all your traffic just block it. This in and of itself demonstrates the purpose.

Also lets be real there are only a handful of adblocking extensions that have most of the market share run by legit players they could trivially vet and whitelist a small number of extensions that are allowed this privilege.

It's not about security its clearly about ruining adblocking. A tiny blocklist that can only be updated with the extensions ensures that it is always trivial to work around blockers. One can simply ask which which version of the extension one has and load ads from a url/host created since.

idbehold• 7 years ago

Perhaps if Google got out of the ad serving business.

wtallis2• 7 years ago

what would it take to convince you that this change really is being made for performance and security reasons, and not to hurt ad blocking?

Is there a security argument for this change? I must have overlooked it.

As for performance: users have a choice about what extensions they use. If Google sincerely believes that their proposed limited content blocking API is adequate, then they can expect that users will notice the performance advantage and move to a new ad blocker even if the old API remains present. That's the main mechanism by which uBlock Origin has largely replaced AdBlock Plus.

On the other hand, in the (fairly likely) case that we find out the new ad blocking API doesn't allow for very thorough blocking, and the ads that make it through slow things down more than our current generation of full-featured blockers, then the lower overhead of the new API really doesn't help end users in any meaningful way.

JohnFen3• 7 years ago

what would it take to convince you that this change really is being made for performance and security reasons, and not to hurt ad blocking?

A strong argument for how that change accomplishes those things, along with evidence.

Google has not been able to provide either of those things.

shawnz• 7 years ago

#1: They would have to give a rationale for the change which actually makes sense. The privacy explanation does not make sense because the observational capabilities of the API are explicitly not being removed. Therefore there is no benefit to user's privacy as a result of the changes. The performance explanation also doesn't make sense if we look at the numbers that adblocker vendors have been publishing in response to these changes.

#2: In light of the backlash to the proposal they would have to actually consider not implementing the change or at least consider some alternative implementations. So far all they have done is say "we've heard your concerns, and we're just going to do it anyway". Many interesting ways have been proposed to achieve the same supposed benefits as what Google claims manifest v3 will provide. But they have not responded to any of those ideas and are blindly persisting with their proposed model with all its downsides. So why even act like this is some kind of open process which involves real developers?

#3: They would need to demonstrate that they are actually concerned about the ability of adblocker vendors to deliver good products. They could have created a transition window from the old API to the new API to see in practice how adblocker vendors choose to use it and what limitations they face. But they haven't done that, instead they announce they're killing the old API the same moment they introduce the new one. That to me demonstrates that they don't really care if it's sufficient for those vendors or not.

elsjaako• 7 years ago

what would it take to convince you that this change really is being made for performance and security reasons, and not to hurt ad blocking?

It's a fair question, but there are several of things that would at least help convince me.

They could demonstrate that they have tried all other solutions that would solve the security issue.

They could demonstrate that the performance benefits of the change would be bigger than the performance benefits of ad blocking.

They could implement a more performant/secure API that still allows full ad blocking.

They could build ad-blocking into chrome (doesn't seem likely to me, but it would convince me).

danShumway3• 7 years ago

If the observational web request API was also deprecated, that wold be a strong indicator that Google's intentions were good.

If Gorhill (and other extension developers) endorsed the changes, that would be a strong indicator to me consider that they might be user-friendly, and that the concerns about them were overblown.

Google could also theoretically just convince me outright. They would need to convince me that extensions were currently hurting my privacy, security, and web experience more than ads. That would be very difficult, but theoretically possible. A blog post that solidly addressed critics point-by-point, rather than simply saying, "no that's wrong", would go a long way.

It's not helpful to Google now, but if the Chrome team built up a reputation for being more thoughtful, I also wouldn't be more likely to take them at their word in the future. I've written about this in the past, but Chrome has been handling developer criticism poorly for a pretty long while, and that pattern eventually reduces developer goodwill. When it comes to trust, everyone is a Bayesian.

That doesn't mean I don't try to consider their arguments, and it doesn't mean by default I assume the worst, but I'm only considering Google's arguments on their own merits. If the changes don't make sense to me, I'm not going to assume by default I should accept them anyway. They can't just say, "trust us, we've seen the numbers."

kryptiskt• 7 years ago

Divest Chrome to an independent foundation. There is nothing cynical in being suspicious of the dominant ad business on the internet misusing their position. There is nothing they can do to alleviate that mistrust short of giving up control (or being forced to in the pending antitrust action).

Nicksil3• 7 years ago

We have no immediate plans to remove blocking webRequest
immediate

We know exactly what this kind of talk means. Don't blow smoke up our ass, Mozilla, just give it to use straight: We'll have `blocking webRequest` for as long as Google allows it.

derefr2• 7 years ago

Or, potentially, it's an equivocation because they want to give Google the appearance of maybe caving later (or at least the inability for Google to claim that they had the opposite appearance), while secretly hoping something changes such that they don't have to cave (and also, possibly, applying pressure below the radar to achieve that end.) Politics!

apazzolini• 7 years ago

I switched from Chrome to Firefox a couple of months ago when the Chrome adblocking changes were announced.

I'll happily find something other than Firefox if it goes down the same route.

Endy2• 7 years ago

Try out Pale Moon or Waterfox.

jerf• 7 years ago

I understand Google's motivation for nuking ad blockers, as well as their motivations for denying every which way that that is what they want to do under whatever security justifications they can bring up, even true ones.

I don't see Mozilla's motivation to remove that at the moment.

I mean, speaking for myself, I'd drop them both and follow a fork of the browser that lets uMatrix work, and that's not something I've considered very many times in the past 20 years. Control over what my browser actually connects to has become a top-3 feature concern for me. I was going to say "I suppose 'working' is technically more important to me", but then I mentally wargamed out whether I'd be willing to use a slightly nonfunctional browser to have uMatrix and noticed that I actually already put up with a slightly nonfunctional browser to use it, because uMatrix already breaks a number of sites until I do some whitelisting.

Even if there's a security impact to extensions having too much access to the web request cycle, there's a security impact to them not having enough access to the web request, too.

diablerouge• 7 years ago

I think that's an important thing to remember - we can always fork it and move on if they choose to remove the blocking webrequest API.

However, how long that fork can persist, remain secure and retain feature parity is an open question. Should Mozilla cave and the community fork be unpopular, Google will definitely have a monopoly on the browser space.

dannyw• 7 years ago

The majority of funding Mozilla’s comes from Google, including receiving a portion of all ad revenue through google search.

A “adopt manifest v3 or we cut your funding in half” could be behind the scenes.

spinningslate• 7 years ago

And in case anyone from Mozilla is listening, this could well be existential for you. Right now, your pro-privacy stance is a principal factor in users choosing Firefox over Chrome.

Follow Google - and all its shady practices - and you will lose a large chunk of those users. Many of them, to use current terminology, are "key influencers": technically savvy people who advise family and friends what to do. Lose them and the outlook is, I suspect, pretty grim.

You're clever people. You'll know this. Google has a good few smart folk too (even if their motivation is questionable). It's easy to see this is difficult for you: Google is your primary funding source. Fail to comply with their wishes, and that funding might well disappear.

As has been noted in other threads, the tension between privacy principles and funding is a huge threat.

For the good of the open web, I desperately want a successful Mozilla, and a technically excellent Firefox at the forefront of a pro-privacy, anti-surveillance re-balancing of the internet.

I don't doubt the difficulty in filling a $300M funding hole. I'd gladly pay $30 per year for a pro-privacy Firefox. Another 9,999,999 is a tall order. On the other hand, you have c250M users...

feanaro3• 7 years ago

Since there is no visible way of leaving a +1 (or a +1000) on HN, I feel like I have to respond to this since it resonates so deeply with me.

Particularly on account of funding, I know I would also gladly pay $30 per year for a privacy, freedom and power use oriented Firefox instead of this new direction they keep taking it in. And so would many of my acquintances.

Perhaps there is merit to organizing a website for people to be able to pledge this.

mav3rick2• 7 years ago

This tech people influencing friends and family lore has been disproven many times. No non tech user is using duck duck go.

Vinnl2• 7 years ago

I wouldn't want to claim that strongly that they won't remove it if I were Mozilla - for all they know, Chrome might still come up with a proper alternative that satisfies the use cases of all blocking extensions, but also performs better. Obviously Firefox would then transition as well.

ohazi• 7 years ago

I hope the ad blockers completely abandon Chrome when this change gets pushed through, rather than attempting to work around it.

Google is using a slow-frog-boil approach to re-desensitize their users to ads, and it's working. The only thing that will work here is a big splash of cold water to the face.

Maybe Chrome losing all of its ad-blockers overnight will finally start making a dent.

cptskippy2• 7 years ago

Unfortunately the owners of the most popular adblocker have successfully created a revenue generating business out of adblocking and aren't about to abandon Chrome.

pvg• 7 years ago

Chrome launched without any support for extensions. chrome.webRequest didn't appear until the end of 2013.

hnaccy• 7 years ago

Outside of uBlock Origin the popular ad blockers are business (see pay for acceptable adds), there's no way they abandon chrome.

feanaro3• 7 years ago

In the absence of a true standard for browser extensions, perhaps Mozilla should consider trying to form one by leading with a strong example instead of weakly implying that they will eventually probably cave to the monopolist.

It's also quite disappointing how there is seemingly no one from Mozilla here, engaging with us on this topic. Instead, the only communication we get is one-sided corporate speak, with no real ability to respond.

If anyone from Mozilla is reading, who do you think will spread Firefox among non-technical users if not the type of crowd that frequents HN?

chucksmash• 7 years ago

In the absence of a true standard for browser extensions, perhaps Mozilla should consider trying to form one by leading with a strong example instead of weakly implying that they will eventually probably cave to the monopolist.

That's exactly what they've tried to do. Firefox exposes a `chrome` namespace object to extensions which is intended to be more or less API compatible with what Chrome provides and added the `browser` namespace object where improvements to the base compatibility are added (e.g. switching from callback based APIs to Promise based APIs). See the bit from the wiki below and the link to the browserext spec:

Mozilla has worked with Microsoft and Opera to implement browser extensions so that developers can write extensions that work across multiple browsers. The preliminary specification[1] matches what Google has implemented in Chrome so that extensions will work on Chrome, Edge, Opera and Firefox.[2]

[1] https://browserext.github.io/browserext/

[2] https://wiki.mozilla.org/WebExtensions/Spec

feanaro3• 7 years ago

Well, it's not enough to try, unfortunately. They have to persist and this talk about the importance of keeping compatibility with Chrome in the context of blocking webRequest removal is not very encouraging.

eh78ssxv2f• 7 years ago

It seems I'm in a minority here, but I was never comfortable installing any adblock extension because the existing request blocking API means that the extension would see all web traffic generated by me (including private URLs that are otherwise not known to anybody but me).

I personally feel that now with manifest 3, I can actually install adblockers since the newer APIs do not share all my web traffic with the extensions.

Can somebody explain why removing blocking API was overall a bad decision by Chrome?

kuzimoto• 7 years ago

Extensions would still be able to use webRequest but only to observe requests, not to modify or block them.

What's the point of an ad blocker if it doesn't block ads?

gorhill• 7 years ago

the newer APIs do not share all my web traffic with the extensions

The webRequest API can observe the URLs you visit without needing blocking permission.

And so does the webNavigation API, the tabs API, history API, content scripts, possibly cookies API and whatever else does not come to my mind.

SquareWheel2• 7 years ago

Shouldn't those be visible in the permissions prompt, prior to installing the extension?

amluto• 7 years ago

I’d like to see this done along the lines of how iOS handles keyboards: allow full web request reading and modification, but only in a sandbox that is per-origin.

zaarn• 7 years ago

uBlock is open source, you can verify that the extension in your browser is the same that is published in the github repository.

The blocking API being removed is an issue because the replacement does not cover all use cases and severely limits what ad blockers can do to intercept filtered content.

Google is obviously aiming to boil the frog slowly and make ad blockers a such terrible experience that Chrome users will not use them.

michaelmrose3• 7 years ago

A humble proposal: A build of firefox that initially differs from Mozillas in that

- it has a different default search engine selection that can be sold in the same way that Mozilla sells this same feature to google presently

- no ads on new tab page

- bundled with ublock origin

The goal being to increase the value of selling the search engine selection while decreasing the value of mozillas in effect siphoning off some of the value of mozillas primary revenue stream.

Such funds could be donated back to Mozilla or used to maintain a fork that doesn't ruin adblocking. Their choice.

phkahler• 7 years ago

I dont like the idea of extensions being able to inject data in either direction.

On top of that, I'm not in favor of extensions doing anything to improve security - I want that in the base browser.

SirensOfTitan• 7 years ago

Mozilla really needs to get that if they compete with Google on Google’s terms, they’re rapidly heading toward extinction.

Mozilla ought to be the browser for a private and usable web, but it seems they have occasional sneezes where you question what they’re doing (this, pocket in recent memory).

echelon• 7 years ago

I'm extremely worried that once Google disables ad blockers in Chrome, websites will wholesale block any and all non-Chrome browsers. Be it through user agent sniffing, feature detection, or fingerprinting, Firefox simply won't work anymore.

The future of the web where Google is in complete control is straight up nightmare fuel. Microsoft in the early 2000s never scared me as much as the future we're headed into does.

This won't be IE versus Netscape since websites are no longer served as plain old HTML. They're messy, thick, and impenetrable javascript blobs--not documents. We're not arguing about websites simply not rendering correctly in the less popular browser. This is a battle for the absolute control over information distribution.

What do we do to prevent what's happening?

Google already shot down XHTML, which was rich with semantics. That was a web written for documents and tools that could query those documents for meaning.

Whatever Google has become needs to be dismantled. The ad company can't be the browser company and phone company. It's a perverse alignment of incentives.

tomComb2• 7 years ago

This won't be IE versus Netscape since...

Well, also since Chrome if open source, cross platform, and standards compliant, and IE was none of those.

And Google (unlike Apple) allows competing browsers, based on modified Chrome code, or entirely different engines.

Soon we will have a good, cross platform Edge browser, thanks to Google, and a menu of browser options in Europe thanks to the EU. (Maybe other countries should push for the same.)

But Chrome if no IE.

And I believe that in Europe they will soon be

levani• 7 years ago

Really interesting what the new Edge is going to do in this regard...

rrix2• 7 years ago

perhaps a more optimistic take on "no immediate plans": there could eventually be an alternate standard for webrequest that addresses Chrome Devs' (perhaps legitimate) privacy concerns around most extensions being able to sniff, modify, and log all of your traffic on the entire web with a single, unobtrusive modal click. There is room to make the web platform more secure without stripping power from the user-agent, surely, or giving bad actors a trivial foothold. Frankly, my concerns around the webrequest API are numerous, the only reason IMO that Chrome isn't deprecating webrequest in Enterprise builds is for corporate spyware.

At the very least a new webrequest spec that is more ergonomic and more safe than the webrequest API (without neuturing adblock) could show whether the emperor has no clothes, vis a vis "Google Adtech is directly influencing Chrome and web platform development" plots
