ExtremeTech has a great article that talks about web browser alternatives, and they look at each one in depth - definately worth a read.
Quote from the article:
“Today, Internet Explorer is rapidly losing market share to the upstart open-source Firefox project. Firefox has garnered more than 20 million downloads, and IE is down to about a 90% market share. Nothing to sneeze at, to be sure, but it’s not hard to see the downward trend. How is Firefox doing this? Why, by building a better browser and giving it away free, of course. Amazingly, about one third of our readers here at ExtremeTech reach us using Firefox. “
