Since upgrading to Windows 8, Firefox locks up when I try to use it, can anyone suggest why please?

We had to download Firefox once we had installed Windows 8. Although we now have a Firefox tile on the new Windows desktop, to enable access to Firefox, whenever we click on it to go to Firefox, we get the option to select Firefox as our default browser. Whether we say Yes or No, the screen then locks up and we have to use Control, Alt and Delete to close it.

The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information. Note: This will cause you to lose any Extensions, Open websites, and some Preferences.

To Reset Firefox do the following:

  1. Go to Firefox > Help > Troubleshooting Information.
  2. Click the "Reset Firefox" button.
  3. Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
  4. Firefox will open with all factory defaults applied.


Further information can be found in the Refresh Firefox - reset add-ons and settings article.

A possible cause is security software (firewall,anti-virus) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.

Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.
