Extensions not loading on startup
I am having an issues with Add-ons and Extensions not loading when I start Firefox, in order to get them working I have to manually disable then enable to get them to load. I have tried disabling each extension to see if one was interfering but to no avail. The only extensions that are not effected by this issue are ones that require Firefox to be restarted whenever they are enabled or disabled.
Using Elementary OS Luna (Ubuntu Linux 32 bit) and Firefox is at its latest version.

It is possible that there is a problem with the file(s) that store the extensions registry.
Delete the extensions.* files (e.g. extensions.json, extensions.sqlite, extensions.ini) and compatibility.ini in the Firefox profile folder to reset the extensions registry.
New files will be created when required.

If you see disabled or not compatible extensions in "Firefox/Tools > Add-ons > Extensions" then click the Tools button at the left end of the Search bar to check if there is a compatibility update available.
You can check for problems with preferences.
Delete possible user.js and numbered prefs-##.js files and rename (or delete) the prefs.js file to reset all prefs to the default value including prefs set via user.js and prefs that are no longer supported in the current Firefox release.
