I currently own a late 2008 15 inch macbook pro. It's my first Mac, and I'm very satisfied with it. Pre-Apple, I used Firefox, and kept on using it when I got the Mac. Some Mac friends suggested I try Safari.. I did and found it ok. I recently downloaded Safari 5 and have been less than impressed. I find the performance extremely sporadic: sometimes very fast, sometimes painfully slow. I have also lost Youtube and Justintv functionality, and since I take online courses the video sites are imperative for me. I've re-loaded Firefox and also Chrome, and over the last three days seem to be leaning towards Chrome for its balance of speed and overall functionality. I'm wondering how you would rate these three web browsers. Overall, which do you think is currently the best & worst? Thank you kindly.
