You can do this via CTRL + SHIFT +T as well.

Can you try to start Firefox in Safe Mode to see if Firefox works properly with no error? You can start Firefox in Safe Mode below:

  • Windows/Mac: Go to Help > Restart with add-ons disabled
  • Linux: Run firefox -safe-mode in the Terminal/Konsole

If Firefox opens up fine with no problems, it's probably one of your extensions that's causing the issue. You can re-enable your add-ons one by one until you find the one that causes the issue upon being re-enabled.

Hi,

Just a heads up, when you restart with add-ons disabled, you shouldn't stay in that mode forever. Firefox's Safe Mode is only used for troubleshooting and shouldn't be used on a daily basis like that.

If Firefox opens up fine with no problems in Safe Mode, it's probably one of your extensions that's causing the issue. You can re-enable your add-ons one by one until you find the one that causes the issue upon being re-enabled.
