Since HN apparently strips out URI fragments I meant to link to this post in the thread (latest post as of writing): https://forum.palemoon.org/viewtopic.php?t=33442#p273914
And worse yet, I was just now told that CF "provide the troubleshooter as a quality-of-life tool and maintain it with best effort." So they aren't even committed to making it work while that was one of the very things that kept coming up in our meeting as it was the only tool remotely available to be able to test Pale Moon (other than testing internally which they seem unwilling to consider, as well) prior to them pushing things to production, so they are already going back on their promises.
I'm really running out of what little patience I have left with CF. They have effectively not addressed our problems, not provided answers, not told me what behaviour is wrong or broken in Pale Moon (according to them), not provided any tools, and are now playing down the one thing we could use in some fashion as "best effort without commitments", while continuing to be gatekeepers for the Internet and access to large swathes of it. EU's Digital Markets Act is pretty clear about how that is not acceptable behaviour -- even if it was written initially to deal with "preferred bundled software" for operating systems, it does lay the groundwork for addressing unfair practices by other types of gatekeepers like CF.
