These so-called point releases contain imperative security upgrades.

ESR releases are maintained for more than a year with important “point releases” that usually follow the regular Firefox releases.

To be more precise, Firefox ESR is an older version of Firefox with a deferred development cycle that aims to offer increased stability at the expense of the latest features.īe that as it may, the ESR line does not fully compromise security towards achieving this goal. For example, imagine a national school system having to change their entire browser system because a new release does not support some important outdated features (but relevant to the system in question) or worse because of a security vulnerability.įound under the moniker of Firefox ESR (stands for Extended Support Release), it’s a browser specifically designed for organizations that require extended support. One of the main issues with mass software deployment within organizations can be the lack of extended support. It may be unknown to many day-to-day users out there that the Mozilla Foundation offers a product specifically aimed at medium to extremely large organizations (schools, universities, and other international businesses).
