When adding an add-on in Firefox 7, it will download it, but never install. It disappears from my add-on list.

I'm on Windows 7 x64 with Firefox 7.

I was trying to get some new add ons from the Firefox page earlier and it was giving me some trouble. I would click the "Add to Firefox" button, the puzzle piece would pop up in the address bar and download the add on and then disappear. I can check my Add-on manager and they will show up with a download bar next to them, but will disappear after a while or when I restart Firefox.

Not sure if this is a server side problem with Mozilla or a bug in my browser. This isn't affecting any add-ons I already have installed.

You can try:

It is possible that there is a problem with the file(s) that store the extensions registry.
Delete the files extensions.* (extensions.sqlite, extensions.ini, extensions.cache, extensions.rdf) 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 do a compatibility check or see if there is an update.

Upgraded to 7.0.1 and deleted those files. Didn't seem to fix anything.

I get the pop up where its downloading the extension, but it just hangs at the end of the download. I don't get the "Restart Firefox" dialogue box, so it's not even really getting to the installation process.

I ended up having to uninstall Firefox, delete my profile and reinstall 7.0.1 with a fresh profile. Solved the problem.
