Today I upgraded to 4.0 but then downgraded again when I couldn't use my Norton toolbar or IDsafe, and my performance on other sites suffered. Now I am attempting to get my Norton toolbar back with the old 3.6, but can't enable the add on. I can't enable or disable any of my add ons, they simply return to previous setting when I restart Firefox. I have tried in both Safemode and regular. Please help.

This can be caused if one of the files that stores details of installed extensions is corrupt.

  1. Open your profile folder, for details of how to find it see https://support.mozilla.com/kb/Profiles
  2. Close Firefox
  3. Delete the following files if they exist, extensions.cache, extensions.rdf, extensions.ini and extensions.sqlite
  4. Re-start Firefox, it will then rebuild the list on installed extensions
