Choosing a Firefox update channel

We currently offer two paths for Firefox updates: Rapid Release and Extended Support Release (ESR).

• Rapid Release: receives major updates every four weeks and minor updates such as crash fixes and security fixes as needed during those four weeks.
• Extended Support Release (ESR): receives major updates on average every 52 weeks with minor updates such as crash fixes, security fixes and policy updates as needed, but at least every four weeks.

In addition to different update cycles, the ESR currently has access to additional policies that are not available on rapid release.

• Changing search engines

We're investigating making those policies available if you are connected to an Active Directory server.

We recommend using the Rapid Release if you can, but understand that there are reasons to use the ESR, particularly around testing of internal applications and policy support.
