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.

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.

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's Firefox 3.5.1 browser is now out with fixes for one critical zero-day vulnerability that first became public earlier this week.

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.

Mozilla is out with the first update of 2010 to its open source Firefox Web browser. Unlike its immediate predecessor, Firefox 3.5.7 is not being issued to fix security issues, but rather is an update for a trio of stability-related bugs.

Mozilla has confirmed that version 3.0 of its popular open source Firefox web browser is approaching its end-of-life (EOL). According to the Mozilla developer's weekly meeting notes, there will be no more updates for Firefox 3.0.x following the release of version 3.0.19, the last security and stability update to the 3.0.x branch.

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.

"The sixth minor update to Mozilla Firefox 3 has been released. Firefox 3.0.6 fixes security vulnerabilities, improves stability, improves the ability for scripted commands to work properly with plugins and resolves a handful of other small bugs..."
