ff5 has too many bugs that are not resolved. that should have been resolved way before they put anything out as the next ff. for example the "submit crash report" always now stays on in ff5. i fixed it by adding "Crash Reporter" then the value of "0" for the data now it stays off purrrmentaltly. honestly think the crash reporter should be removed and that will boost performance. uther wize i hast seen no increase in speed over ff3.6.16
