I click on the arrow for the drop down menu and it won't drop down? I can sometimes scroll through using the arrows on my keyboard.

Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

IT SEEMS TO WORK OK IF i START IT IN SAFE MODE, SO DOES THAT MEAN i NO LONGER CAN START IT NORMALLY AGAIN, DO I HAVE TO KEEP STARTING IN SAFE MODE OR IS THERE A WAY TO FIX IT FROM SAFE MODE?

You can try to disable hardware acceleration in Firefox.

  • Options/Preferences -> General: Performance
    remove checkmark: [ ] "Use recommended performance settings"
    "Use hardware acceleration when available"

You need to close and restart Firefox after toggling this setting.

You can check if there is an update for your graphics display driver and check for hardware acceleration related issues.


If it works in Safe Mode and in normal mode with all extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) disabled then try to find which extension is causing the problem by enabling one extension at a time until the problem reappears.

Close and restart Firefox after each change via one of these:

  • "3-bar" menu button -> Exit (Power button)
  • Windows: File -> Exit
  • Mac: Firefox -> Quit Firefox
  • Linux: File -> Quit
