Rated 5 out of 5 stars

Perfect, does exactly what I expect. I cannot for the life of me fathom why this feature was removed from Firefox, and with more than 21K people bothering to look for and install this plugin, clearly I'm not the only one who missed it.

Look I know for those who like tabs, it is absolutely impossible to fathom why someone would prefer to use their browser another way but please try to remember that everyone has their own preference and don't take away choices.

Personally I've tried to like tabs but I just don't. I often have multiple browser windows open and alt-tab between them. I've already got a perfectly usable task bar in my OS and the browser tabs are a redundant second task bar specific to the browser.

This review is for a previous version of the add-on (1.2.1-signed.1-signed).
