Apple made the last security update applicable to OS X 10.11 available in July 2018. Why has Firefox ended support for OS X 10.9, 10.10 and 10.11 users?Īlthough Apple does not have a public policy governing security updates for older OS X releases, its practice is to support the most recent three releases. Affected users will not receive any further security updates. This was done to provide security updates until the final Firefox 78 ESR update (version 78.15.0esr) was released on October 5, 2021. These users were moved to the Firefox Extended Support Release (ESR) channel by an application update.
