Rated 4 out of 5 stars

edit, have to say this is a very useful addon, really like having the browser minimize on startup, and being able to minimize from the Esc keys also great, really intuitive option to have

to iynque above, if its triggering a popup that your about to close xx number of tabs, like its going to close Firefox instead of minimize, thats just cause youve got the Options/Tabs "Warn me when closing window with multiple tabs" ticked. Youll notice if you click "Cancel" on that popup, it proceeds to minimize tho. Untick that option and itll minimize without any more
