works great with method listed below. The only thing I can add is be patient when an account syncs for the first time, it seems to take a couple of minute during which T-bird is slow. (I added 2 accounts, each with 4 calenders each and it took 3-4 minutes for them to sync and for T-bird to become normally responsive).
Best part is two-factor authentication works.
