78.0.0 and 78.0.1 trashed "display info" from no longer matches displays accurate info.CC and BCC not normal to many radical changes. Don't you beta this stuff?
"Always prefer display name over message header" doesn't work any more. "From" no longer displays "Display" info. Can't sort on display name as it no longer matches what was in previous emails. How do I revert to old version? and shut off auto updates?

Odd - I found no bug reports suggesting other users have had problems. And I am not able to reproduce.
Are you seeing all your addressbooks? Do you see any errors in tools > developer > error console after starting thunderbird or clicking on an email?
