Rated 4 out of 5 stars

windows xp - on FF3.0b - works verynicely: choose "convert web page to application", decide if you want toolbars etc or not, save file - poof, you have a shortcut to launch the web page in a separate FF browser window.

personally not sure what the fuss is all about - except it allows for launching separate browser processes from the O/S, and allows hiding of browser chrome. So, instead of having 9 tabs I now have 9 browsers open, thus not running the risk of crashing the whole session due to a script bug in one site.

This review is for a previous version of the add-on (0.2).
