All of my tabs has a red vertical line to the right of my "X" on the Tab Bar. Currently, I'm using 40.0.3. I've tried installing with a beta version, reinstalling the stable version, removing my anti-virus and disabling my extensions. None of these actions worked. Any other ideas?

Can you attach a screenshot?

  • Use a compressed image type like PNG or JPG to save the screenshot
  • Make sure that you do not exceed the maximum size of 1 MB

Did you try Safe Mode?

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
