Well it is not really "Travel Technology" but I installed FF 6 and can honestly say that it has been a POS. Java scripts constantly stopped responding or not working at all, it was noticeably slower than FF 5, and having just ripped it out and gone back to FF 5, I can say that the scripts that were not working, are now working, and it is much much speedier. So, if you are thinking of going to FF 6 (Windows) then test it first is my advice.
