Sync failed, bookmarks lost Rated 1 out of 5 stars

In a matter of hours, all of my bookmarks were obliterated automatically. Luckily, I had made a backup before syncing started. I think it is a problem with the Firefox (22) version of this addon, but losing years worth of site bookmarks and countless hours of researching them is not acceptable. Never installing this again.

This review is for a previous version of the add-on (4.2.1.1-signed).
