Rated 5 out of 5 stars
It works for Firefox version 3.5.8, but I want to make a suggestion to include somewhere the "close window" and the "minimize window" buttons that are normally found on the right side of the windows bar. Maybe add a really small version of the windows chrome on top, from where the browser can be handled. It sais here that this extension "adds also two new buttons - Close Application and Minimize" but I can't find such buttons.
Also it would be good to provide a toolbar button from which to be able to replace the Control+F2 keys. It sais here that this is provided, but I can't find it.
I think this tool is good. I know that some people use Google Chrome over Firefox because of the larger area it provides, so this improves things.
