Google promises that the latest stable release of Chrome offers faster start-up, a small speed uptick of Chrome's V8 JavaScript engine, and support for MathML (Mathematical Markup Language), which renders math formulas and symbols on browser pages.

Chrome 24 also patched 24 vulnerabilities. Three of them were reported to Google by a outside researchers, who received $6,000 for their efforts as part of the search company's bounty program. Two of the four were Facebook researchers who together earned $4,000 for uncovering and reporting a bug in Chrome's "same origin policy," a security provision intended to block browser-based languages, including JavaScript, hosted on one domain from running on another.

Chrome 24 also included a new version of Adobe's Flash Player that contained a critical patch.
