Firefox’s back button drop-down

Just getting used to working with new Firefox 4, I noticed something was missing: the small drop-down menu that used to be next to the back/forward buttons, which allowed you to go back in your history faster than one page at a time. Apparently, the presence of this menu was considered a bug, hence it was removed.

I use that quite a lot, so I was just a little bit upset that it was gone, but as always in the land of open software, someone has come up with a solution. This cute little add-on restores the history drop-down menu. Nice!

(And yes, I know a right-click on the back button does exactly the same thing, but on my laptop, when my right hand is over the touchpad, having to click the right-side button is just not convenient.)
