Well, this might be as much of a Firefox bug as a PF one...or just that the forum software isn't ready for whatever just changed in the last browser upgrade. I just upgraded to Firefox 3.0.10 on Mac OS 10.5.7 and in threads, the only button appearing under posts is the quote button. The edit, multiquote and report buttons all went missing! I don't know if that can be fixed or if I just need to wait for Firefox to be fixed. Fortunately, everything still works in Safari.
