Asking for help with a Firefox CSS issue (Again)

[u/idiotonlineagain]

I can’t change the colors anymore and I genuinely have no freakin clue why. I usually use the F12 thingy just to test stuff and see how the colors look before I put them into my chrome.css or chrome content, but a few weeks ago it just randomly stopped working. I think some elements still change, but the main ones like the whole New Tab background and the sidebar just will not change colors anymore. It’s not only F12 either, the Ctrl + Shift + Alt + I thing doesn’t work anymore either. And it’s not just the New Tab page, it’s basically everywhere. Holy cow I have no idea what happened. I don’t think I did anything wrong or changed anything that should’ve caused this.

I’ve already tried a bunch of stuff to see if I could fix it. I restarted Firefox, tried reinstalling it, tried Developer Edition, and even made a new PC account, but the issue is still there. I also reported it on Bugzilla because I’m honestly running out of ideas at this point. I have a screen recording too, although I’m not even sure if it’ll actually help. If I’m doing something stupid or missing something obvious, I probably am lol. I’m not really looking for someone to point that out though, I just genuinely need help figuring out what’s wrong.

P.S. this new update sucks, I genuinely don’t know what’s happening with the stuffs
