Except where noted, everything here applies only to Firefox 115. Firefox 115 is the next ESR so, going forward, only fixes will be backported to the Firefox 102 ESR.

Bug Fixes

• If a preference was locked by one policy, it could be accidentally unlocked by another policy. This was fixed in bug 1772503.

Policies

• The UserMessaging policy had the ability to lock preferences, but it was missing from the documentation. This has been added.
• The FlashPlugin policy has been removed.
• A recent change enabled revealing passwords for password fields via a context menu. If you need to remove this behavior, you can set the preference layout.forms.reveal-password-context-menu.enabled to false using the Preferences policy.

Special Notes

There are two 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.
