Since Firefox has been updated, the interface is completely unusable. The frame does not render properly. I can use Firefox only in safe-mode with the terminal. The new WebRender seems to be the problem.

What did I do then ?

  • I entered apt purge firefox for full removal and reinstall -> Didn't work.
  • I disabled in about:preferences hardware acceleration -> Didn't work
  • Downgrade to Firefox 88 -> Worked.

I love the new interface and the new render process. But if I can't use it on my home workstation, things are going to be hard for me.

I added a screenshot to show the problem.

Thanks by advance !

You can try to disable WebRender.

Hi

Are you using an add-on to get that transparent effect?

As mentionned. It resolved the problem for the moment. I'll wait the next update to try with the webrender enabled.
