Rated 4 out of 5 stars
Great program, but noticed v 3.7.8 is having more and more sync issues. everytime I open Firefox. I look down at status bar it shows a red x indicating sync error. I'm using portable firefox 3.6.8 . I installed 3.7.9 just now. anyway, first real issues I've had with it. otherwise excellent.This review is for a previous version of the add-on (3.7.8).
