Google’s Chrome browser has only been on the market for 16 months, but it has already taken a good share of the market and beat out Safari for the number three spot. Safari, for the first time ever, is now ranked fourth. By the end of December, Chrome was up at 4.63% market share whereas Safari fell to about 4.46%. Of course, the big boost likely came from the fact that Chrome Beta became officially available for Mac and Linux. Top dogs are still Mozilla Firefox and Microsoft Internet Explorer, with IE8 still at the top but failing to see any real growth. So tell us, what browser are you currently using and why (speed, extensions, apps, etc)?
