Something seems to have changed dramatically in the underbelly of Firefox 3 in the last week or two. Testing a nightly build, I've found that the list of Friends at Facebook disappears completely. No, no, no, I do have friends and they are visible using Safari, but something about the javascript in the Facebook friends page has stopped pulling the data for the friends with the latest Firefox 3 nightlies.

UPDATE: Sat 1 March 2008: 11:51pm HKT, the build from this morning is pulling the friends information again.
