I successfully used Weave for a while on two different computers. Wonderful add-on!

But I just got a new computer, and every time I try to run Weave to sync my existing bookmarks and passwords to my new computer, Firefox freezes, and I have to execute a forced quit.

I'm running FF 3.6.3 (the latest version), and Weave 1.2.3 (also the latest). I have tried disabling all my other FF add-ons, and even closing all the tabs except a single blank tab, to make sure nothing is interfering with the Weave process. I have a solid internet connection, and it happens anyway.

I'll try again one more time overnight in case I'm just stopping the process prematurely, but I only kill FF after Windows Task Manager shows it as Not Responding. Is there anything I can do? Or is this just a bug that needs to be ironed out in Weave or FF?
