Contributor guide
Research direction
Review PR #420173 and the package metadata for Mozilla.Thunderbird and Mozilla.Thunderbird.ESR, then reproduce the proposed upgrade with `winget upgrade` after installing the standard release. Done means WinGet no longer proposes changing a standard Thunderbird installation to the ESR track.
