(solutions) 1-Update Firefox

Every Firefox release includes a number of fixes for crashes that people have reported. Making sure you have the latest version may fix your crash.

2-Update your Internet Security software

Make sure you have the latest version of your Internet security software (including firewalls, antivirus programs, anti-spyware programs, and more).


3-Check to see if the crash happens in safe mode

If updating software didn't work or if Firefox crashes on startup, use the steps below to test whether the crash happens in Firefox Safe Mode or not and then follow the instructions in the recommended articles.

Note: You can also start Firefox in Safe Mode by holding down the shift key while starting Firefox.
