Rated 3 out of 5 stars
Found another problem. It doesn't work in text boxes.
Sadly, that can't be fixed - the default Firefox "search" option doesn't exist in a textbox. If that makes it three stars, I suggest using another addon.

The major annoyance has been fixed. Removed search engines are no more cluttering the menu.This review is for a previous version of the add-on (1.0).
