Greetings. While trying to fix a broken Thunderbird/Enigmail installation on my wife's Windows laptop, I found the cause to be a new feature in Thunderbird 78, installed recently without notice: that it will not support Enigmail. The new version also appears to have no obvious way to import openpgp keys, and it appears the developers do not plan to support that, at least for secret and signed public keys, nor any intention to adhere to the "Web of Trust" infrastructure. I still have TB 68 on the Debian machines, but expect that will go away by Bullseye release, since Mozilla's support for it apparently will end late this year.
I elected to use Thunderbird a number of years ago because it has a relatively decent UI, downloads and removes the messages from my ISP's servers, and with Enigmail had reasonably good PGP integration. I'm sure there are others, but it's 10 - 20 years since I used them (fetchmail + mutt, IIRC). I would welcome suggested alternatives. An additional desired feature, if known, would be any capability to ingest old messages from Thunderbird. Thanks, Tom Dial
