Except where noted, everything here applies to both Firefox 80 and the Firefox 78.2 ESR.

Policies

• The Permissions policy has been updated to allow you to configure permissions for virtual reality notifications.

Other

• A preference has been added to turn off the confirmation dialog when you submit a form from an insecure context to a secure context. This was added in bug 436200. It is not yet available via policy. The preference name is security.warn_submit_secure_to_insecure.

Special Notes

• As mentioned in previous release notes, Firefox 78 is the last major release with support for macOS versions 10.9, 10.10 and 10.11. Users of these macOS versions will be supported through Firefox ESR 78.x for the coming year. You can read more about this here.

• The next ESR based on Firefox 68 (68.12) which will be released August 25, 2020 will be the last Firefox 68 based ESR unless there is a security issue before September 22, 2020. Users of Firefox 68 ESR will start to be automatically upgraded to the Firefox 78 ESR when Firefox ESR 78.3 is released on September 22, 2020.
