Firefox pink visual display errors and bugs (Flickering and others)

more options

So something off has been happening to firefox with me recently, I am having like visual errors and firefox has been acting weird lately, I remember yesterday when I was going to bed I noticed one of my tabs in firefox was flickering pink and what not, And I kinda thought it was a bug and closed itt off then closed firefox off and went to bed, Cue today same thing happened expect the effect was much more bigger, The screen was flickering alot with pink, Some display errors, And I am noticing pink lines that are still there ontop of my tabs and browser entirely, The other windows are not affected by it, Something is off, The screen was flickering in a way like I can see my desktop entirely along with the browser page and so on

I actually do not know the reason but I do feel like its firefox related, Yes I disabeled hardware acceleration and so far I still see the pink lines, Yet nothing is happening aside from the pink lines and I still don't trust it

I don't know what to do need help, Thank you very much

Click the menu button New Fx Menu and select Options on Windows or Preferences on Mac or Linux.

   Select the Advanced panel and then the General tab.
   Uncheck Use hardware acceleration when available.
   Restart Firefox and see if the problems persist.

Are you using of the built-in themes? You could try switching from System to Light or Dark and see whether either of those is more stable. Ref. Use themes to change the look of Firefox.
