[Bug 65609] Re: "installLocation has no properties" error in nsExtensionManager.js during install/update of extensions

[John Stevenson]

I had exactly the same problem as Gene Mosher, in that I wanted to
revert to FF2 to continue using various extensions that are not yet
compatible with FF3.

This was on a box-fresh install of Ubuntu Hardy.

I had no extensions.rdf to delete

I tried the patch, but that just moved the problem further down to line
7647.

Then I found this thread, among others:

Deleting /home/$username/.mozilla/ worked for me.
