Ultimately I just need Firefox to always support about:config, manifest v2 compatibility, and userChrome.css and userContent.css.
That said, usually changes like these break my extremely minimal redesign and configs I have on my desktop. So... boo, Mozilla, boo....
userContent.css is absolutely essential for me. I use that to limit the size of images on Thunderbird.
Isn't userchrome.cc already deprecated for quite some time?
It'd be news to me, I've used the same userChrome.css and userContent.css for years now and I keep my Gentoo Linux desktop up to date with weekly updates, so the Firefox I'm using is confirmed to be the latest version.
Additionally, a quick search on ddg reveals no recent mentions nor plans for deprecation of the feature as far as I can tell.
I found this Reddit discussion
The timeline fits (pre-covid), but I got the word wrong. I thought userchrome would've been killed of by now.
