My add-ons act like they're installed, but don't show up. This didn't happen until after I installed FF4, had lots of trouble with it, and had to go back to FF3.5.5. Suddenly my add-ons don't work. How can I fix this?
I installed FF4 on both my laptop and PC, but I kept getting kicked offline, especially from Facebook. I then uninstalled FF4 and went back to FF3.5.5 (on the PC) and FF 3.6 on the laptop. This solved my connectivity issues, but add-ons are now acting up. No add-ons at all show up on the PC, and only Personas show on the laptop. When I try to install Forecast Fox and Colorful Tabs, I get the "install now" message and the message to restart FF, which I do. When it repaints, the add-ons are just not there. I expect it's something I'm doing wrong, but I don't know what it is. Java is updated. Any pointers? TIA!

This can be caused if one of the files that stores details of installed extensions is corrupt.
- Open your profile folder, for details of how to find it see https://support.mozilla.com/kb/Profiles
- Close Firefox
- Delete the following files if they exist, extensions.cache, extensions.rdf, extensions.ini and extensions.sqlite
- Re-start Firefox, it will then rebuild the list on installed extensions
