Google released Chrome version 5 developer builds for Windows and Mac on Friday. "The devchannel has been updated to 5.0.307.1 for Windows and Mac," said the firm. On the Windows side of the fence, the default downloads directory on Vista and Windows 7 can now be used. Google has added a content settings window to the latest rough-round-the-edges iteration of its browser. The tool gives surfers more control over changing and policing their plug-ins, cookies, pop-ups, images and JavaScript. The search engine giant’s latest developer build, intended to be tested by hardcore coders, also comes with several bug fixes.
