They should have done this three years ago, before Google's better, faster, less leaky browser started to gain traction.

You know, I wish I could see that. But I can use Firefox regularly with 80+ tabs without any hitch. Chromium starts getting unresponsive somewhere between 10 and 30 depending on the content.

You're not the first person that's said that; what's your setup?

I've had consistent memory problems on WinXP, Win7, and OSX, all of them muscled up machines, especially when using JS intensive apps or leveraging Krumo (yes, I'm a PHP programmer, but I promise I can code, breathe and drool at the same time).

Edit: I do use Firebug, so I'm loading up JS resource usage.

Already discussed and with more information:

They said the same thing when 7 came out... I'm on 8 and it still eats 1.2GB+ of RAM out of 4 at the end of the day. I'm still using it only because of Firebug.

These tweaks will be in FF11 or thereabouts...

I've got a dozen addons, and I keep gmail, to-do list etc. open all day long. I've had it open for several days now with at least 10 tabs open and it's using less than 0.5 GB out of 8. What's your usage that gets it over 1 GB?

Also, what can you do with Firebug that you can't do with Chrome's "inspector"?

zuppy2• 15 years ago

Usually I keep in tabs Google Reader, Facebook (not always on), Gmail, sometimes Groove Shark plus many random sites (maybe ~25 tabs).

...as with extensions: AdBlock Plus, Download Statusbar, Flashblock, iReader, Live Http Headers and TinEye.

I just took this screenshot of the task manager: http://dl.dropbox.com/u/2311018/temp/shot.jpg

I honestly don't remember what I don't like about web inspector, I've tried it a while ago and I couldn't do all the things I wanted. Maybe I'll give it another shot sometimes.

edit: my biggest issue with chrome was that for few years you couldn't see the source code of a page sent through a post request: http://code.google.com/p/chromium/issues/detail?id=523 They say it's fixed now, maybe it is...

Trust me, Firebug is still a lot better than inspector. And while I get sniped by the occasional Web Inspector bug, but firebug is pretty close to flawless.

If memory serves, they've said the same thing since about version 4.

As a bunch of other people in the comments have noted, Firefox can take a huge amount of memory, the one thing they also have in common.... is the Firebug extension. It should come as no surprise to them then that Firefox is not actually leaking the memory... Firebug is. A quick Google search for "Firebug memory leak" will lead to multiple examples of massive Firebug memory leaks.

It's a bummer that Firefox gets the blame for Firebug's memory leaks. If people would like to avoid that, the best thing would be to use Firefox's multiple profile feature so that they activate/install Firebug in a Developer profile, and keep their general browsing profile without Firebug. It's rather amazing just how much, and how fast Firebug can leak memory as using a separate profile will make abundantly clear.

Browsers are platforms, wouldn't be the same to blame Firefox lack of developer environment?

windle2• 15 years ago

Good point, I forgot to mention that Firefox is expanding the developer tools it comes with:

Also, it hasn't landed in Nightly yet, but there's some really slick dev tools that are being built into Firefox:

There's some nice CSS and Javascript tools coming too, but I can't seem to find any URL's on them at the moment.

I didn't know this, but to be fair webkit's inspector is as good as firebug for my needs and doesn't leak.

Maybe the answer is to roll firebug into default firefox to force the issue and get the leaks addressed?

Too little, too late. I switched to Chrome a year ago.

orthecreedence• 15 years ago

I hate to say it, but everybody is LEAVING firefox already because of this. Closing it and restarting every hour got old. Even with the latest versions it does this.

The fact that they keep claiming "it's a feature!!" is what made me the most angry. Firefox is now useless to me as a web browser, I use it only in limited cases for web development. Chrome has completely replaced it.

"Oh but it's your add-ons." No, it's not. Even disabling my add-ons and starting with a new profile Firefox eventually consumes more and more memory. "Well that's what happens because it's saving history." Ok, force restart it. It will open all the same tabs, each with the same amount of history for that tab...5% of the memory usage of before restarting it.

The thing is a bloated beast. I really do hope they fix it. I loved firefox when I used to use it, but it's not very useful to me as it is (firebug or not).
