IS&T now recommends Firefox Extended Support Release (ESR) 17 to the MIT community. The ESR release of Firefox is designed for institutions like MIT: it facilitates long-term support for accessing various websites and lets organizations test and maintain internal web applications for business continuity.

Unlike the rapid-release cycle of the regular version of Firefox, major Firefox ESR releases will be distributed and maintained for approximately one year and will enable users to decide when to upgrade. Firefox ESR versions will address high-risk/high-impact security vulnerabilities through minor point releases.

How to Obtain
Community members can obtain Firefox ESR online from the IS&T Software Grid.

Note: When you install Firefox 17 ESR, choose the option to replace your existing installation of Firefox. Bookmarks or browsing history will not be lost, but some extensions and other add-ons might not work until updates for them are available.

More information about Firefox ESR can be found on the Mozilla Firefox ESR Overview page.
