Rated 4 out of 5 stars

Great Plugin!

4 of 5 stars because of 2 little things:
* Rightclick context menu doesnt seem to work at FF3.6
* Popup windows (those without menu bar and that kinda stuff) are also minimized instead of closed. I'd love to have a setting that only minimizes the "real" windows. I'm not sure but I think the other minimize plugins can do that

This review is for a previous version of the add-on (0.5.4).
