Hi,

After recent update i've begun to see weird black squares on all pages. They appear randomly and I can't figure out how to solve this. They disappear once i scroll the page or switch to another tab and go back again. Any help is appreaciated.

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

  • switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Themes
  • do NOT click the "Refresh Firefox" button on the Safe Mode start window
