Over the past three weeks, since I updated my Firefox version to 148.0.2 (aarch64), a black or white rectangle appears at the top of all websites and prevents me from accessing some links on those sites.

I refreshed and cleared the cache, and it worked for a while, but then it appeared again on every single website.

It makes it unusable that, for the first time in 15 years, I might have to switch to another browser if I can't solve it.

In the attached picture, you can see that the place line covers the top of the site and cuts off the Firefox logo and the links above.

Any solution is welcome

Start Firefox in Troubleshoot Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration or if userChrome.css/userContent.css is causing the problem.

  • switch to the Default System theme: "3-bar" menu button or Tools -> Add-ons -> Themes
  • do NOT click "Refresh Firefox" in the Troubleshoot Mode start window
