I’ve been having a lot of problems for about three days now. Whenever I open certain pages, I sometimes get rendering issues where the graphical part of the site doesn’t load properly. The page appears completely gray, but it’s actually loaded — if I click randomly on the screen I can see the links change, so the page is responding even though it isn’t being drawn correctly.

On X and Twitch this happens often. With Twitch, while I’m watching a live stream, if an ad starts or I switch to another stream, the screen goes completely black. When this happens, the whole browser is affected — even if I have multiple tabs open across my two monitors. The top window buttons (minimize, maximize, close) also change style and look like the old Internet Explorer ones.

If I start Firefox in troubleshooting mode, X opens correctly, but Twitch still has the same black screen problem during streams.

Here’s what I’ve already tried:

  • clearing cookies and cache
  • disabling all extensions
  • turning hardware acceleration off and on
  • using troubleshooting mode
  • trying other fixes I found online

None of these solutions have worked so far.

I have a 360hz 2k monitor and 1080p classic 60hz monitor 5060 r7 7800x3d 32gb ram

I installed two versions of Firefox on my PC. (I did this because an update caused me to lose my data!) Now, I would like to uninstall one of the 2 versions! The situation, however, is this: Mozilla Firefox (x64 it) - 91.0.2 : acttual version: 115.6.0 (7/1/2024) installation of 28/8/2021 (\exe91)


Mozilla Firefox 85.0 (x64 it) - 85.0 .  : acttual version: 115.20.0 (5/2/2025) installation of 3/3/2024 (\exe85)


Mozilla Firefox ESR (x64 it) - 115.9.1 : installation of 29/3/2024 (\exe91)


Mozilla Firefox ESR (x64 it) - 115.20.0 : installation of 5/2/2025 (\exe85)


Each installation was done in different directories. I hope this trick will allow me to uninstall a version without causing any problems... Can anyone confirm this? Thanks for the reply! Regards.
