Next week, March 18th, in parallel of the new major release of Firefox, we will be publishing our next stable release (24.4.0).

For those who are not familiar with ESR (Extended Support Release), Mozilla maintains a specific version of Firefox for about a year. In these releases, we only backport high-risk/high-impact security vulnerabilities.

This version is mainly used by companies which don't want to update their versions of Firefox every 6 weeks but also some Linux distributions which needs to be maintained for a while.

We published the pre release of Firefox ESR 24.4.0 for testing. No need to go a full qualification but testing of internal websites are welcome.

Please file bugs for any critical regressions you find and make sure to set the need-info? flag on release-mgmt@mozilla.com so that we have visibility into the issue.

Alternatively, you can directly email release-mgmt@mozilla.com or the enterprise list.
