My extensions disappeared

Yesterday I had 7 extensions installed in Firefox 15.01. Today they are gone, although I see the in the profile folder. The extensions folder is empty. I'm really steamed, because some of these I rely on heavily. What happened?

Re: My extensions disappeared

It is possible that there is a problem with the file(s) that store the extensions registry.

Delete the files extensions.* (e.g. extensions.sqlite, extensions.ini, extensions.cache) 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, not compatible, extensions in "Tools > Add-ons > Extensions" then click the Tools button at the left side of the Search Bar (or click the "Find Updates" button in older Firefox versions) to check if there is a compatibility update available.

If this hasn't helped then also try to delete the addons.sqlite file.

I think it has something to do with Sync. I have 3 computers at various locations, and I probably did a sync from the wrong one oe in the wrong direction.  :-(
