Firefox - was working fine, then computer spontaneously re-booted and now won't open.

Won't let me uninstall because says it is running.

Tried re-install anyway and it looked like it worked, but no luck - still won't open.

Hi : Please Open Windows Task Manager and End all Firefox Processes then uninstall Firefox. Then Delete the Mozilla Firefox Folders in C:\Program Files , C:\Program Files(x86) & C:\ProgramData Then restart system. Then run Windows Disk Cleanup. (Note: This should be Pinned and run Weekly, If never done below expect 10's of gig's) Then run it again and click the button that says Cleanup System Files. Note: your Firefox Profile is saved. But you should make a back up before you do :

Reinstall with Current Release Firefox 59.0.2 with a Full Version Installer

Can also give this a try for the reboot :

  • Repair System Registry and Files

Find the Dos Prompt Right or Powershell Click and Run as Administrator then : Copy/Paste to Dos Window : DISM /Online /Cleanup-Image /RestoreHealth then hit Enter. Reboot when completed. Note : DISM goes up to Microsoft for new ones.

Please let us know if this solved your issue or if need further assistance.
