Brief - feed reading extension for Firefox

I was so relieved and happy that you updated Brief for the new FireFox. Thank you so much! I would've missed it so much; I use it so many times each day to keep up with the blogs I'm subscribed to. It's the best RSS reader I've ever found, and especially for FireFox.

After I installed the update, though, all my favorites from Brief went missing (all my starred pages). And I can't find my backups. Is there any way to get them back? (I'm assuming not.)

So, I want to make sure I backup Brief from now on. To do that manually, I go into my Firefox profile folder in Documents and Settings, and then make a copy of brief.sqlite. Is that right?

thank you.
