If you haven't already tried Ibai's solution, I'd be happy to take a look at your Sync log.

I'm having this issue as well. Sync encountered an error while syncing: Unknown error. Sync will automatically retry this action.

I've tried to remedy this issue nine ways to Sunday. Reset my Sync, Changed my Password, Unlinked and Relinked--still no dice. It's really getting annoying! Help!

jcwestberry: if you take a look in about:sync-log, find the latest one named "error...", and send it to me, we'll be able to give a little more advice.
