Great minimize add-on! Rated 5 out of 5 stars
I am using Windows 7 and yes, this add-on does better than the other minimize add-ons because it works more like Windows 7.
The big thing for me is that most programs with a minimize option allow clicking the X to minimize, as does this add-on. The other Thunderbird minimize icon disables the X - which is annoying because that's different from most other applications on Windows.
