Firefox ESR

The new super-fast Firefox, with features for IT professionals to configure and deploy Firefox in their organization.

Mozilla will offer an Extended Support Release (ESR) based on a regular release of Firefox for a desktop for use by organizations including schools, universities, businesses and others who need extended support for mass deployments.
Mozilla Firefox ESR is meant for organizations that manage their client desktops, including schools, businesses and other institutions that want to offer Firefox. Users who want to get the latest features, performance enhancements and technologies in their browsing experience should download Firefox for personal use, as these improvements will only be available to ESR users several development cycles after being made available in Firefox for a desktop.
