I'd be willing to help test. I just tried to install twitbin with FF3B3 and upon restart none of my previously open tabs would load content. I currently have FF set to allow all extensions to install so I can continue to use a few extensions I really enjoy but have not updated for FF3Bx yet.
Easy!
Using firefox or flock check out http://twitbin.com and click on the download link.
You will need to make sure you allow popups for the site.
You should get a notification asking you to authorize.
Hit yes.
Then next time you boot up firefox/flock you should have the little birdie icon in your menubar.
