Problem installing Rated 3 out of 5 stars

My whole navbar went missing after installing this addon. It all ended up being placed into my customize toolbarbutton storage window with the urlbar,searchbar,reload,stop,back/forward buttons. I uninstalled this addon and there is still the problem of navbar and toolbarbuttons being placed into the storage window. Every time after restart I have to place them back on to the navbar... and the addon has been uninstalled.
EDIT:
I just tried to install this addon in another profile with no other addons and it installed fine and operated great... so it must be another addon that clashes with this addon causing the installation problem. Would like to be able to have this addon with all my other addons though.

This review is for a previous version of the add-on (1.6.1).
