Mozilla is advancing its plans to release a version of Firefox tailored for organizations whose IT departments manage it for their employees from a central console. This version of Firefox, to be called ESR (Extended Support Release), will be updated at a much slower pace than the regular version of the browser, in order to give IT departments enough time to appropriately test, certify and adopt the new releases.

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.

The proposal to develop Firefox ESR has now been escalated from a “proposal” to what Mozilla calls “a plan of action,” Mozilla official said in a blog post on Tuesday. The new version of ESR will be available once a year, providing the clients with a version of Firefox that receives security updates but does not make changes to the Web or Firefox Add-ons platform. Mozilla is working closely with its Enterprise User Working Group on this project. “Over the last few months Mozilla gets great feedback on the initial proposal from the Mozilla community and strongly believe that the ESR meets that goal.
