Mozilla on Wednesday released Firefox 3.04, a security and stability update to its popular open source Web browser.
The update addresses nine Security Advisories, some of which cover multiple vulnerabilities. Four are rated "critical," two are rated "high," two are rated "important," and one is rated "low."
Critical flaws typically allow an attacker to execute code remotely or crash the user's system.
In addition to stability improvements, Firefox 3.04 is available in Icelandic and Thai. And it includes beta releases for Bulgarian, Esperanto, Estonian, Latvian, Occitan, and Welsh.
Mozilla also updated Firefox 2 to version 18.104.22.168. The update address 11 Security Advisories, six of them rated "critical."
The company also advises users of Firefox 2 to upgrade to version 3.
Firefox reached a global market share of 20% for two out of the four weeks last month, an event that Ken Kovash, Mozilla's metrics chief, characterized as a "historic milestone."
Google on Tuesday released Google Chrome 0.4.154.18 for developers. Among other changes, the update moves all configuration options for features that might send data to another service into one place to make privacy choices clearer.
Chrome enjoyed a brief surge of popularity following its introduction in September, and for a time displaced Opera as the fourth-most-popular browser in the world. But in October, Chrome usage flagged and Opera resumed its place on the fourth rung of the browser ladder. Presumably, Chrome will represent more of a challenge to Firefox, and perhaps Internet Explorer, following a stable 1.0 release.
