Firefox has stopped working. I closed it in the normal way, but the next time I tried to run it, it would not work. I uninstalled, and then reinstalled it, without success. I uninstalled it again; deleted the Firefox folders from appdata/Mozilla Program Files and Program Files (x86) folders. I then rebooted, and reinstalled Firefox again, but it still won't run. I tried opening it in safe mode, and I tried to run the Profile Editor by using the -p extension to firefox.exe in an attempt to recreate my profile, but still it would not run. I am at my wits' end - please help!

Since have been uninstalling and installing please then uninstall 1 more time.

Then download a Full Version Installer here : https://www.mozilla.org/en-US/firefox/all/
