I love an update when it makes something better. (Isn't that the point?) In the case of Thunderbird 78.4.0, what were they thinking? You now have to hit Cc and Bcc on each email you write rather than have those fields show up by default, as has been the setup for years? Why? For multiple Cc's or Bcc's, you have to separate them by a semicolon rather than have a fresh line for each, which to me is easier to read? What's the point of ''that'' change? Is there no way to fix these (ahem) improvements? Terrible! Thanks to anyone who can smooth this over for me. Also, in passing, I don't appreciate having auto-update checked by default. That's not how I have ever configured Thunderbird, and settings ought to stay as they were unless there's a reason and the user is notified.
