Delivering a Mozilla Firefox Extended Support Release

We are pleased to announce that the proposal for an Extended Support Release (ESR) of Firefox is now a plan of action. The ESR version of Firefox is for use by enterprises, public institutions, universities and other organizations that centrally manage their Firefox deployments. Releases of the ESR will occur once a year, providing these organizations with a version of Firefox that receives security updates but does not make changes to the Web or Firefox Add-ons platform. We have worked with many organizations to ensure that the ESR balances their need for the latest security updates with the desire to have a lighter application certification burden.

Online life is evolving faster than ever and it’s imperative that Mozilla delivers improvements to the Web and to Firefox more quickly to reflect this. Providing updates to Firefox more frequently allows us to secure users against emerging threats and provide the platform for innovation that today’s rich and compelling Web experiences demand. However, this created challenges for organizations that have to deliver lots of mission-critical applications through Firefox, so we worked closely with the Mozilla Enterprise User Working Group to develop the Mozilla Firefox ESR plan.

Mozilla is committed to providing the best Web experience for people everywhere, and our goal for the Firefox ESR is to make it simpler for companies, public institutions, organizations, and institutions that manage their desktops to deploy Firefox in those environments. Over the last few months we received great feedback on the initial proposal from the Mozilla community and strongly believe that the ESR meets that goal.

Implementation specifics will be posted within a week to the mozilla.dev.planning newsgroup and the EWG mailing list. If you’re interested in the ESR or discussions around deploying Firefox in a managed environment, we’d encourage you to join the Mozilla Enterprise Working Group and participate in its discussions and monthly conference calls.
