Comment 8 for bug 79352

This problem still exists for me in Gutsy. Agreed that sudo is a feature, but how does this play out with individual user's prefs and customizations of the extensions?

Anyway, only two extensions installed globally with correct permissions for me in Gutsy. The others installed correctly to /usr/lib but with incorrect permissions for use by a non-root user. Manually adjusting the permissions did not make the extensions usable for non-root user, either. If this is an error in the extension maintainer's packaging, then it seems like a bit of a nightmare to get fixed. Can anyone provide more info about what's at play?

The 'lack of useful output' is IMO something that should be corrected.
