Firefox extended support version for corporations will be supported for about one year from introduction

Firefox will be 7 times faster during 2011, half of memory usageWe have made a dramatic evolution, but that was supported by the rapid release that we will upgrade major version every six weeks. However, on the other hand, frequent upgrades were a burden to corporate users, and they had a disadvantage that it was difficult to keep using Firefox.

In order to overcome this, Mozilla interacted with corporate users in the working group and decided to provide Extended Support (ESR) version Firefox to periodically perform only security and stability issues. Provision will start from the end of January 2012.

By doing this, each Firefox release cycle looks like the following.


First, the support of the old version (Firefox 3.6 line) will end on April 24, 2012.

The preview release called "Aurora" is testing versions two ahead of the official version. For example, since Firefox 9 is currently being released, Firefox 11 has been tested on Aurora. What I received feedback from Aurora is Beta, which is testing the version one ahead of the official version.

When this beta version of Firefox 10 is released as the official version on January 31, 2012, ESR 10 will be released as well. Firefox will be updated every six weeks and will be expanded afterwards. However, regarding ESR, security and stability are only corrected in the form of "10.0.1" and "10.0.2" in 2013 Support will be held for about one year until February 12th.

The next major update of ESR 10 will be ESR 17 on 20th November 2012 and will be released in the form of an introduction period of 12 weeks and an operation period of 42 weeks thereafter.

In addition, Thunderbird, Mozilla's mail software, will also release an extended support version just like Firefox.
