Rated 5 out of 5 stars

Works perfectly for me in Windows 7. It solves some problems I had with other similar addons.

With MinimizeToTray Plus I can minimize-when-closing Firefox in different ways: clicking on close button, closing the taskbar button with Right Mouse Button and also with Alt-F4 keystroke. All of them works great.

This review is for a previous version of the add-on (1.0.7).
