Comment 10 for bug 772845

@Mike

I use the packages from the ubuntu-mozilla-daily ppa - so i had thunderbird 3.4a1pre, the version from the mozilla daily ppa that superceded 3.3a4pre - and the plugin at 0.4. That all changed a while back, when 3.4/3.3 was renamed on the ppa as 7.0a1 (or 'thunderbird-trunk') and the unity launcher integration addon was compatible only with 3.3a4, so wouldn't work on any other version, even with compatibility checking off.

Actually, now i've went back to the latest 3.1.x from the ppa (3.1.11pre) and have switched to the addon "Unity unread count" (version 1.03) which gives me the unread count in unity i desired :D
