Except where noted, everything here applies only to Firefox 143 and the Firefox 140.3 ESR. Firefox 140 is the next ESR so, going forward, no enterprise changes will be backported to Firefox 128 ESR.

Special Notes

Firefox 128 ESR goes out of support with this release. Firefox 128 ESR users will be upgraded to the Firefox 140 ESR.

We are extending Firefox 115 ESR support for Windows 7/8 and macOS 10.12/10.13/10.14 users until March 2026.

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