The attached xpi file has an install.rdf with an <em:package> that points to a non-existent location (in this case the jar is empty, though when I originally saw this it was due to a typo). After attempting to install the xpi, every start of Firefox will result in a "Finishing Extension Installation" dialog that never disappears. Deleting the extensions sub-folder in the profile is the easiest way of clearing the problem. This could be considered to be an extension bug rather than a Firefox bug, but I think that FF should handle the situation more gracefully so that the problem can't be used as any sort of "attack" (though maybe with the white-list that has been discussed in various places this won't be problem). I have no idea if -no-extensions will bypass this problem as that feature seems broken at the moment, I'll file a bug on that in a minute.

I always forget how powerful extensions are, using this bug as an "attack" would be pretty stupid, since a properly installed extension could do a lot more harm. Anyway it would still be nice if broken install.rdf files were handled better.
Created attachment 150441 [details] ieview XPI causing installer hang Another XPI which causes the same problem. Trying to upgrade IEView to live within the 0.9 setup, but I'm running into this wall. Obviously, something's wrong with my XPI layout or the install.rdf, but there's no feedback as to what.

Thanks - solves the install problem for this extension. Nonetheless, the behavior when running into bonehead install mistakes like mine is sub-optimal.
I ran into the same issue and filed bug 246369. IMHO, Firefox should gracefully skip invalid extension install manifests.
I have tried to delete the subfolders, but it still hangs. I then deleted the two extension sub-folders, but it still hangs. I then reinstalled over the initial installation, and it still hangs. Any suggestions?
Please try removing and/or completely renaming any of the following directories you might have: %APPDATA%\Firefox (ie. C:\Documents and Settings\Username\Application Data\Firefox) %APPDATA%\Mozilla And try again, with a completely clean profile. Often the culprits are the chrome directory and the extensions directory - but the XUL and localstore data files can get corrupted too, in my experience. -[Unknown]
