Mozilla's current plan is to release only one more update to Firefox 2, version 2.0.0.19.Mozilla Firefox, or simply Firefox, is a free and open-source web browser developed by the Mozilla Foundation and its subsidiary, the Mozilla Corporation. Last week, Mozilla released Firefox 2.0.0.18 and Firefox 3.0.4, addressing a dozen security flaws, half of which were ranked as critical. Earlier this month, a system administrator for the University of Bergen commented that a bug related to the use of network drives had meant the organization could not install Firefox 3.įirefox 2 is still receiving significant numbers of bug-fixes in new releases.

The browser's new location bar has also come in for criticism. Some users have noted that Firefox 3 appears to be more prone to crashing than the older browser, and has problems with using too much memory. Mozilla is pressing on with the transition despite criticisms of Firefox 3 from some quarters, including some organizations that have found the newer browser unusable due to particular bugs. All users are strongly encouraged to upgrade to Firefox 3."

Mozilla confirmed the move on the web page devoted to older versions of its software, stating: "Firefox 2.0.0.x will be maintained with security and stability updates until mid-December, 2008. The move will affect a range of third-party Gecko-based browsers, such as SeaMonkey, the Mac-only Camino and the Unix/Linux browser Galeon. Support will also cease for the Gecko 1.8 layout engine that underlies both Firefox 2 and the Thunderbird 2 email client.
