When I open TB, under "Accounts", it only shows the option "Create a new account". Option: "View settings for this account" is NOT shown.
When I open TB, I no longer see any information about the TB account I've used for years. Instead, the main menu shows only "Accounts" -- "Create a new account - Email, Chat, Newsgroups, Feeds". Option: "View settings for this account" is NOT shown.
Also the main menu does NOT show "Email - Read messages, Write a New Message" or "Advanced features", etc..
The actual emails pertaining to the TB account I've used for years are still present under the "Users --> xxxxyyyy --> AppData --> Roaming --> Thunderbird' folder.
