This works great on FF3.6 and TB3 on Win7_x64. This extension is a must have for all Win7 users.

There is only one drawback with Firefox: Since Firefox allows to open several windows, you are no longer able to close one out of these windows by clicking on the close [X] button. You have to use the menu item "close window" or Ctrl+Shift+W for that.
Nevertheless 5 stars from me. :)
