Try the Xmarks repair option, it should hopefully fix the issue.

Open the Xmarks settings dialog, go to the Advanced panel and then click on the Repair button. This will force a synchronization and should correct any problems with the data stored on the Xmarks server.

Thanks to TonyE, but it did not fix the problem. It acted like it was starting to sync, but it just kept spinning forever and I had to force quit Firefox. [email protected]
