This seems to happen after I've used Firefox for a long time, or I've had several tabs open. The block covers all windows, whatever application I choose, and can't be dragged. I have to close Firefox and reopen it to remove it.

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.

  • Switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance
  • Do NOT click the Reset button on the Safe Mode start window

Do a history clean. Most of the problems happen in firefox due to lot of history data. if you upload a image or link to image of the issue it will be usefull to find what is the actual problem.
