Special Notes

Firefox ESR 115

Firefox 115 is the next ESR and will be released on July 4, 2023. Going forward, we will only be backporting security fixes to the Firefox 102 ESR.

If you use the ESR, we strongly recommend that you start testing with Firefox Beta to see if there are any issues you have with the new ESR.

There are three more planned releases of Firefox 102 ESR, and then it will go out of support on September 26, 2023. Users will then be automatically upgraded to the Firefox 115 ESR.

If you need to prevent upgrades for any reason, you can use the new AppUpdatePin policy.
