Mozilla is updating its Firefox 3.x browser to version 3.0.12 for five critical security vulnerabilities. All of the issues have already been addressed in the latest Firefox 3.5.1 update which came out last week.

In a bid to respond to a critical security vulnerability, Mozilla has released a new version of its open source Firefox Web browser ahead of schedule.

Mozilla is updating its Firefox Web browser with new technology that is targeted at making the open source browser more stable. The Firefox 3.6.4 release also includes fixes for four critical security vulnerabilities.

Just days after the arrival of Firefox 3.6.7, Mozilla has released version 3.6.8 of its open source web browser to close a single critical vulnerability which was introduced in the previous update

Mozilla Firefox 2.0.0.5 has been released and is currently being distributed to Firefox 2 users via the application's built-in software update system. The browser upgrade fixes several security bugs, which are detailed in the Firefox 2.0.0.5 section of the Mozilla Foundation Security Advisories page.

Mozilla Corp. yesterday patched 10 vulnerabilities, half of them marked "critical," in its open-source browser as it updated Firefox to Version 2.0.0.13. The new Mozilla Messaging Inc. spin-off, however, was not able to provide a matching update to its Thunderbird e-mail client, which shares five of the Firefox flaws that were fixed.

As announced, Mozilla has released the first update for Firefox 3.5, prompted by the disclosure of a critical security flaw related to TraceMonkey, the new JavaScript optimizer, earlier this week.

Mozilla is out this week with Firefox 3.5.9 and 3.0.19 updates, fixing multiple security vulnerabilities in the open source Web browser's two branches, while announcing that the older of the two branches is being phased out.

Mozilla has patched a pair of security vulnerabilities in its Firefox Web browser just in time for its release of security tools at the Black Hat security conference in Las Vegas this week.
