After upgrading Mozilla Firefox to a newer version, the previously installed add-ons do not work anymore.

Just follow these steps to fix this:

1. Close Firefox
2. Open Windows Explorer and find the Firefox profile folder (note that this is a hidden folder):
   

   [drive]:\Users\[user]\AppData\Roaming\Mozilla\Firefox\Profiles\[profile]\

3. Delete or rename the following files:
   • compatibility.ini
   • extensions.cache
   • extensions.ini
   • extensions.rdf
4. Restart Firefox.
