Comment 33 for bug 397211

We should probably just close this bug as 'invalid':
 * The maintainers said there would be a backport from Karmic after they updated its branding and all I see is libprotobuf3
 * They obviously don't care about making firefox-3.5 useful for an average user which makes me wonder why they put it in Jaunty's repo to begin with
 * Instead of fixing a non-UI flaw, they would rather attempt to police the Internet

Basically if you want a truly integrated and properly branded Firefox 3.5 you'll have to dist-upgrade to Karmic Alpha 6. Sorry everyone but hopefully they've fixed any crazy dependencies and there aren't any bad drivers that could brick your hardware. I don't really know what else we can do.
