Comment 7 for bug 267382

I looked into the issue a bit deeper and I was wrong about the firefox-2 vs firefox-3 data.

The problem is that the extensions moved to universe and that gnome-app-install does not show universe extensions by default. In hardy that worked because in the dekstop file, the "component" was set to main.

If the extensions get good security support, then I'm fine with removing that check.
