Currently Bugzilla (well, bugzilla.mozilla.org) has Platform: Macintosh OS: All or Platfrom: Macintosh OS: Mac System X.x - where X is 8, 9, 8.5 etc. This means there's no way to say a bug occurs on all versions of Mac OS where mozilla runs (currently 8.5 through 10.1?). Platform: Macintosh, OS: All doesn't cut in as we also run on LinuxPPC and who knows which other Unix derivatives which have PowerPC ports, probably shortly to include Darwin, if they ever work the kinks out. Given this is the most common case when filing Mac bugs (occurs on all version of Mac OS where Mozilla runs) it's annoying. Then again, there's no Win32 entry either so maybe its intentional? Filing as unconfirmed...
oops. ok, so its actually "New". Sorry!
Fwiw bugzilla.openwatcom.org handled this problem
