When I close my tabs using mouse3 as always it will create "blank tab" on tab panel which can dissapear by themself or I need to move cursor to tab place to make it dissapear. It's ver annoying, any variants how to fix it? I attached a foto of this blank tab... PS I checked if I close tab by clicking X on the right side of tab the blank tab also appear.

Don't see the screenshot.

See this support article. How do I create a screenshot of my problem? It is best to use a compressed image type like PNG or JPG to save the screenshot and make sure that you do not exceed a maximum file size of 1 MB.

Then use the Browse .... button below the Post a Reply text box to upload the screenshot.

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
