Incredible solution to clutter. Rated 5 out of 5 stars

Fantastic Add-on. It has cleared up my Bookmarks Toolbar by lumping Google's services. This is an incredible bit of code. Everyone should get it. If I had any kind of disposable income, I'd donate to the project.

This review is for a previous version of the add-on (2.1.6).  This user has other reviews of this add-on.
