At this point in timeRapid release calendarAccording to the release schedule from Ver10 to Ver13 is as follows.

Tuesday, January 31, 2012: Firefox 10
Tuesday, March 13, 2012: Firefox 11
Tuesday, April 24, 2012: Firefox 12
Tuesday, June 5, 2012: Firefox 13

Furthermore, as a schedule for the next fiscal year, there is a suggestion that Firefox 10 will provide "Extended Support Release", which was long awaited by corporate users and others. This ESR version will be refrained from adding new functions by upgrading one after the other as usual, while continuing to apply security updates etc. on the other hand, it is possible to test the environment that operates stably, test various add-ons It will be able to take over time as well. If it is realized it will be possible to use it even with users like "You are updating one after another, but you are watching on add-ons and other various relationships" or "You can not move one step from Firefox 3.6".

Details about extended support will be as follows.

Here are the main new features of Firefox 10 «Mozilla Developer Street (modest)

Although it is not officially decided yet at the moment, it is suggested that Firefox 10, the first release of 2012, will begin offering Extended Support Release version (ESR version below). In ESR version, at the same time as normal Firefox version upgrade, only minor modifications related to security and stability are performed, and minor version up without minor version change is provided.

In the current proposal, since the ESR version carries out a major version upgrade for every 7 versions of Firefox and at least 2 versions support both old and new versions, each version is between 9 versions × 6 weeks = 54 weeks = 1 year We will continue to support it (see above figure).

Please consider stable users upgrading to ESR version Firefox 10 if you are an enterprise user of Firefox 3.6 because stable versions that do not change function or speed are required.

Although the ESR version is a functionally stable version, the version with the most stable operation becomes the regular version of Firefox. Unless you must avoid functional modifications, please use the latest Firefox which continues to improve all the memory usage reduction, responsiveness improvement, security and stability as well as new functions.

There is no plan to offer ESR version Firefox for Android.
