Great idea but I won't use it. Rated 3 out of 5 stars
I've been searching for something like this forever.
My main problem with this addon is, that it can only be used in the bookmarks drop-down-menu and not in the bookmarks-sidebar.
I have very very many bookmarks so using the drop-down menu is impractical. If it would work with the sidebar I would give five stars.
Another problem is that ratings cannot be synced to other computers via xmarks but I don't know how this could be solved.
Thanks for the feature suggestions
Thank you for trying it out and providing feedback. I will take your suggestions and incorporate them into the next version. I agree that syncing ratings would be beneficial and I will look into XMarks or Firefox sync to provide this.
