I'm new to mac, recently bought the new aluminum macbook and was wondering if it is more secure to use firefox vs safari. I noticed that scrolling is way more smooth in safari than in firefox and the fact I have more of the page since safari has thinner borders and also the loading thing is right in the address bar. More to it, with the new trackpad i can use the multitouch capabilities that is only built in safari but not firefox. Could you guys let me know which one is better to use? Also, I installed Sophos antivirus (which is free for UCLA students) on my mac, is that of any help? or does it catch windows viruses only?
