Google has rolled out a new version of its Chrome Web browser and has said that a version of the Mac browser will be out in a few months.

Version 3.0 of Chrome for PCs brings improvements to the browser's interface, including faster performance and "themes" that allow users to customise how the browser looks. Chrome holds a distant No. 4, with a market share of roughly 2.8 percent and apparently Google is hoping the new version of the browser will double that.

The internet search company is readying a battery of updates, along with efforts to forge new distribution partnerships it hopes will soon make Chrome a much more significant player. A Mac version of Chrome is currently available for testing and will be released by the year's end. Quite how Google thinks that it will convince Mac users to use a browser which does not have the blessing of Steve Jobs and is similar to their own Safari is not clear.

People like Chrome because of the speed and Verson 3 goes like the clappers, but has not managed to get the wide appeal of Firefox as an alternative to Firefox. According to market research firm Net Applications, Internet Explorer had roughly 67 percent of the worldwide browser market in August, while the Mozilla foundation's Firefox had 23 percent and Apple's Safari browser had 4 percent.
