Why do my add-ons keep disappearing
Every week to 10 days, I open Firefox and find that all my add-ons other than Norton have disappeared. It is getting tiresome to have to continually reinstall add-ons I checked the profile as suggested and there is only one, a default set the day the add-ons disappear. I am using Windows 7 home edition, and I have been using Firefox in Sandboxie, but they disappear even in the one not sandboxed. This has been going on for about two months

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.
See "Corrupt extension files":

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.
If this hasn't helped then also delete possible addons.json and addons.sqlite files.
