Rated 5 out of 5 stars
This is one of the best add-ons on Firefox. Unfortunately, Quieturl does not function when you use Menu Editor: (https://addons.mozilla.org/en-US/firefox/addon/710/)
When you install Menu Editor, Quieturl will work fine at first, but as soon as you actually use Menu Editor to edit the menu, Quieturl stops catching links. Please, please fix this.
