How do I enable an add-on in Firefox safe mode?

So recently I have had a problem with Firefox crashing all the time and found out it was an add-on that was causing the problem.

I have tried opening Firefox in safe-mode to disable add-ons but they are already disabled, so I want to know how to enable an add-on and then to permanently disable it so Firefox will open normally again. . .

I have already tried to permanently disable all add-ons by using the Firefox options box but nothing happens after I click on the 'make changes and restart firefox' button. After I click it nothing happens and it remains frozen. (Safe mode Window)

So to make things short, how do I enable an add-on in Firefox safe mode?

Check and tell if its working.

In Firefox 4 and later Safe mode disables extensions and also disables hardware acceleration.

  • Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"

If disabling hardware acceleration works then check if there is an update available for your graphics display driver.


You should still see a Disable button or Enable button (if you disabled them all) in the extension Manager (Tools > Add-ons > Extensions) if you start Firefox in Save mode.
