Mozilla has dumped Firefox 3.7 from the release schedule, replacing it with regular features updates for version 3.6 of the browser.

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 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.

According to the developers, the Firefox updates address a total of twelve issues, including 9 critical security bugs, one high-risk and a moderate XSS hazard. Many of the issues could potentially lead to the remote execution of arbitrary code on a victim's system.

As part of Mozilla’s ongoing stability and security update process, Firefox 3.5.7 and Firefox 3.0.17 are now available for Windows, Mac, and Linux as free downloads:

Pressure from Google Chrome and, increasingly, from other main players in the web-browser market is forcing Mozilla to change its ways. Most notably, it's starting to rethink its update schedule and system for Firefox and favoring small incremental updates, a la Chrome, instead of major releases months or years apart.

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