The ESR is focused on stability and not new features.ĮSR was based on the 10.0, 17.0, 24.0, 31.0 38.0, 45.0, 52.0 and now 60.0 Releases. The 52 ESR will have nine major updates because the current ESR is being based on 60.0 Release and not 59.0.ĮSR was made for Enterprise users in mind as they generally did not like to test and deploy major Releases so often. The legacy 52 ESR will have last major update 52.9.0esr on June 26 (along with 61.0 and 60.1.0esr) and then 52 ESR will be EOL on Sept 5 (with no more updates) when 62.0 is Released along with 60.2.0esr.ĮSR in general gets eight major updates and when a security and or allowed stability fix(es) is needed there may be one or more minor update for that major update if need be. The 60.0 ESR however will continue to be supported with a update to 60.1.0esr then. For example the current 60.0.x Release will be made EOL when 61.0 is Released. Releases are only supported until the next major Release.

Mozilla wanted to put a stop to these delays and have much better control of what went in and the schedule. It was pretty common to have two if not even three versions of Release branches in overlap of still getting updates to complicate things. Mozilla provides the data on all builds on a public service called Buildhub, which has a web API.Rapid Release is a term that started as of Firefox 5.0 and on for Releases that you download from The Releases before used to often take forever to come out as Firefox 4.0 for example had delays for over a year.

Using the build ID, we can find out whether the build is ESR or not.

The browser’s open-source design and inspiring history as part of the Free Software movement are part of the appeal. Every day, around 500 million people use the browser, and there are plenty of good reasons for this.
