Unneeded add on Rated 1 out of 5 stars

I hate to break it to everyone so enamored with this extension, but this adds no functionality to Firefox that isn't already there, plus FF's feature does NOT lose the history.

Did you know you can simply drag and drop a tab from one window to another, and all of it's history stays with it? Even if your windows are on top of each other, simply drag the tab to the other FF tab in your task bar and it will automaitcally open the other window. Drop the tab in that window wherever you want it, and all back buttons and history are still there. Simple.

What do we need this for?

This review is for a previous version of the add-on (1.2.8).
