Chrome is clean and lean. Firefox was my go to browser for years. Then changes were made and I didn't like the gui. IE is a no way browser for me, with auto updates I no longer have a reason to use it. Bing is more like spyware to me than anything.
Google is the future with the "cloud" being forced on everyone.
I switched from FF to Chrome soon after Chrome came out, and been loving it. Recently, though I switched out for my work PC. Chrome's Add block sucks. After the 2nd time my work PC got a virus from a banner add on a forum, I tried FF again. No problems since, and I am liking FF. No adds, plus it reloads pages are a lot faster...
