VERY convenient Rated 4 out of 5 stars
It's still a bit glitchy, but this is a Godsend for someone who runs 5+ different FireFoxes. Any problems I've encountered have been minor and usually fixed by refreshing the page of the FoxMarks website. I wish that something like this existed for Internet Explorer (not that I use it anymore, since I got FireFox Portable.)This review is for a previous version of the add-on (1.0.1).
