Get firefox browser for mac way better! and its free.

i downloaded firefox and when i downloaded the os 2 and put it on the memory card and when i put it in the mp it doesn't even show up at all. what you think it is ? this shhh it is beyond me man. does it matter that im using a mac ? i doubt it because all other os downloads i did were on my mac. i also did the press option when clicking the link and got the same result. somebody holla at me.
