My bookmarks were erased Rated 2 out of 5 stars

I've had some issues with xmarks recently that has caused me to switch to Firefox sync. I got on my computer today to find out that on the last sync, xmarks deleted every bookmark I had edited within the last month. Half my bookmarks--gone. Thankfully I had them backed up in Chrome. If you're using a bookmark sync (or even if you're not), make sure you export your bookmarks every-so-often to avoid this! This isn't the first problem I've had with xmarks, but it was certainly the biggest and worst.

This review is for a previous version of the add-on (4.1.3).
