Does firefox have a power saving or performance mode turned on which might cause issues if like me in edge it was cauasing low fps on streaming videos and not nice, turned that crap off and was fine. Also if u have access to flags like chrome does etc u can try forcing it to use dx9 rendering instead of whatever is dafault as that used to clear up alof of issues on chrome when i used it so i didnt have to turn hw acceleration off. Not sure if it will help mind but just ideas to try i guess.
Have you tried a nightly build, maybe it might help?
https://www.mozilla.org/en-US/firefox/134.0a1/releasenotes/ Or perhaps do a backup and reinstall ff it might somehow fix something that caused it?
Also try troubleshoot mode maybe, could be a addon causing it or something else that is configured diff from default.
https://support.mozilla.org/en-US/kb/diagnose-firefox-issues-using-troubleshoot-mode Double check if u use a dark or light themed change isnt causing it if u use any of that stuff. Also if u use windows scaling, if u use other than 100% check that.
Do u use
https://www.userchrome.org/ to modifty anything, i wonder if u have that and delete it it might make a fresh default one that might fix it, who knows i just mention as saw this topic causing some grey on the browser somewhere and they fixed it with that file and some editing.
