LOL - when you swipe on your MBP how can internet freeze - otherwise I would not have been able to answer this question. I bet you mean to say your MBP browser freezes. I never had that problem and not sure which browser you are using? Safari or Firefox or Chrome. Try other browsers and see if that solves the problem. If it did solve, then one of setting on your browser is messing up with OS level settings.

Not sure if you have upgraded the newer version of Safari ( i think 5.2?) which came out with 10.7.3 update.

The best solution is to buy a real computer and throw away your "laptop". Macs are for children and art history students.
