Except where noted, everything here applies to both Firefox 130 and the Firefox 128.2 ESR. Firefox 128 is the next ESR so, going forward, no enterprise changes will be backported to Firefox 115 ESR.

Policies

• The PrivateBrowsingModeAvailability policy had been added to provide better control over private browsing. (This will be in the next ESR.)

Special Notes

This is the last major release of the Firefox 115 ESR for enterprises. Firefox 115 ESR goes out of support for enterprises on October 1, 2024. At that time Firefox 115 ESR users will be upgraded to the Firefox 128 ESR.

We are extending Firefox 115 support for Windows 7/8 users.

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