Comment 2 for bug 267382

After upgrading to firefox-3.0.2+build3+nobinonly-0ubuntu2 (intrepid) and ubufox-0.6~b1-0ubuntu1 it seem like today I can install every extension with synaptic or from the terminal, but still, the install/remove extensions list is empty. Wait for the update of the gnome-app-install files. Thanks Alexander, you're right, it's not an ubufox issue.
