Rated 4 out of 5 stars

I agree with the previous reviewer. This works great (though e-bay seems broken right now, even in real IE 8's webslices). My only complaint is the amount of space taken in the browser for this. Can this button be placed somewhere else ... anywhere else ... other than as a single button on an entire otherwise empty toolbar? Think: Status bar (bottom), another button on the main toolbar, on the bookmarks bar, etc. The best case scenario is an option to allow it to appear in the status bar, OR if you don't want that, it can be dragged wherever you want much like the other movable buttons. Still, thank you for bringing this feature to Firefox before IE even went live with it.
