> I thought Mozilla severed ties with Thunderbird years ago.

Sort of, but not really. T'bird is now under a subsidiary of Mozilla. According to Wikipedia:

Operated by MZLA Technologies Corporation, a subsidiary of the Mozilla Foundation, Thunderbird is an independent, community-driven project that is managed and overseen by the Thunderbird Council, which is elected by the Thunderbird community.
