Comment 5 for bug 871325

I've filed a bug in Launchpad (https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/871325), I've asked if they want to add UnityFox to their addon (actually they have two different addons, one for Unity globalmenu integration and one for other things, like apt support).
If their reply will be negative, I'll try to implement the progress bar directly into Firefox.
