Rated 4 out of 5 stars
This addon has made bookmark tags infinitely more useful as a way of organizing and finding my bookmarks. This sort of functionality should have been included in the browser.
I really am eager to see it updated for 3.1, though. I've migrated to 3.1b2 and don't intend to go back to 3.0. This is the only addon I really use that hasn't been updated and can't be made to work properly by jiggling the maxversion. Believe me, I'm missing it greatly!!
It probably is more deserving of 5 stars, but something about it feels as if the layout could probably be improved just a bit. I'd go 4.5 if that were an option.
I appreciate the volunteer time on the part of the author. I realize beta 2 is still carrying potential to change the addon interfaces. Still, I'm hoping for my sanity's sake that the author of this addon is working on a FF 3.1 compatible version. My eternal gratitude if he is.
