Rated 2 out of 5 stars

I've used XMarks for a couple of years and it worked perfectly until about a month ago then it started to duplicate folders instead of syncing them. It was a great add-on until then. Customer service doesn't respond at the GetSatisfaction support forum. Don't install this one. You'll spend your time fixing bookmarks that XMarks will then mess up again.

This review is for a previous version of the add-on (3.9.2.1-signed).
