I have not open firefox in a very long time. The last time i used firefox, it was not properly been closed (many tabs were not been closed and my laptop was been left a while). Since then, every time i open up firefox, it says "well this is embarassing" and whether i want to recover my search or not. But whenever it is opened, i can barely move the arrow to click on anything. i was intended to refresh it, but it starts to slow down the whole system. i can't even close the window nor refresh it. even if i manage to close the window, my computer is still slow. i can't even move the arrow. so how to reset my firefox without even open it?

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?

Try to start Firefox with the about:blank page by creating a copy of the current Firefox desktop shortcut. Add a space and -url "about:blank" to the target field in the Properties.
