Sir, thank you for this addon! It's just what I wanted. I have about 5-10 profiles of Firefox, few of them created for testing addons and webdevelopment. Now I will install this addon to all of them. It's perfect and simplifies navigation in bookmark area. I love it and I will write about this addon in my article about Firefox.
its great so far feature suggest: open in new tab from bookmarks doesnt change places apptab focus,, feature suggest: incontent options & download dialogs this features are allready planned for firefox 10 !!
