My computer had an unexpected shutdown. At that time, Mozilla was open and working with no problems. After the shutdown I restarted the computer but Mozilla wouldn't open. Simply after clicking the icon (in Startuo programs r any shortcut) nothing happens. I tried to uninstall it with Windows Uninstaller whowever I didn't manage - I kept receiving the message to close the program before uninstalling. So I used an external uninstaller with which I managed to uninstall the program and installed it all over again however this didn't solve the problem- I still cannot open it. Can you advise me some solution?

See:

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the add-ons is causing the problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).

  • Don't make any changes on the Safe mode start window.

See:

Create a new profile as a test to check if your current profile is causing the problems.
See Basic Troubleshooting: Make a new profile

If that new profile works then you can transfer some files from the old profile to that new profile (be careful not to copy corrupted files)
