Comment 8 for bug 1895643

Indeed security updates will force the move to 78 sooner or later. I'm myself a happy user of 78 nowadays but can understand the Enigmail change will cause grey hairs even if most of the little bugs have been fixed.

In my case, I think I upgraded when 78.2.2 was out, I needed to tinker a bit before I realized I needed to manually go to Manage Identities of my account and select my key there for each ddress before my setup was complete. The upgrade didn't automatically enable using the OpenPGP key associated with the e-mail addresses other than the account's main one.

Here are some resources to read through just in case people find this bug when they encounter the migration:
