Chrome 23 also patched 14 vulnerabilities, six of them ranked "high," Google's second-most-serious threat rating, seven pegged as "medium" and one as "low."
Of the 14 bugs, six were reported by three outside researchers, who were awarded a total of $9,000 in bounties. So far this year, Google has paid out more than $360,000 in rewards, including three payments of $60,000 each for winners of its Pwnium hacking contest. The most recent of those checks went to a teenage researcher known only as "Pinkie Pie," who hijacked the browser at the Hack In The Box security conference last month.
Also included in Chrome 23, Fischman said, are improvements to the browser's graphics rendering technology, which he claimed could extend a notebook's battery life by up to 25% under heavy surfing loads.
Users can download Chrome 23 from this website. If Google's browser is already installed, it will update automatically in the background to the new version.
Chrome puts the 'Do Not Track' setting under the Privacy section of its Settings screen, but unlike Microsoft's IE10, leaves it unchecked by default.
