My friend has just bought a Mac Book Pro and he likes it and all. He said I could play around with it and install programs. I saw that he did not have firefox on his computer so I installed it. I showed him what I installed and he was fine with everything except firefox. I use Mac, Windows, and Linux all the time and this is the only internet browser that works on all systems. (Yeah I know there is opera but it is not me) Plus I love the extinctions. Well he seemed to go off on me never to install that again because it exploits holes that are in windows XP. He some how reasoned that Windows had its problem because of firefox. I serious doubt that firefox has any major security flaw on OS X. Can anyone enlighten me if there are any security problems with firefox on OS X. or if there is some reason I should always use Safari over Firefox?
