I chose to initiate a short test and browse using each one of today popular web browsers (Safari, Opera, Firefox, Internet Explorer and Chrome) at www.abelski.com, a relatively heavy website.
Safari and Chrome seem to be the fastest web browsers. Up to 4 times faster than Internet Explorer. The next fastest browser (right after those two) is Opera. You can watch the short tests below.
Internet Explorer Web Browser
Chrome Web Browser
