Project:Mozilla

The Gentoo Mozilla team is responsible for all Mozilla related packages in Gentoo.

Stable Firefox/Thunderbird packages
Since our resources are quite limited, and stabilization realistically should take at least 4 weeks between Mozilla releases, we decided to only stabilize ESR (Extended Support Release) versions of Firefox. Thunderbird's upstream stable releases are based on Firefox ESR. For planned release cycles of different Firefox browsers, please see https://wiki.mozilla.org/Release_Management/Calendar

And for a matching NSS-ESR, see https://wiki.mozilla.org/NSS:Release_Versions

Thunderbirds past release notes are available at https://www.thunderbird.net/en-US/thunderbird/releases/
