User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:130.0) Gecko/20100101 Firefox/130.0

Steps to reproduce:

  1. Download Thunderbird for macOS from thunderbird.net
  2. Configure Thunderbird with a fastmail account
  3. Click the "New Message" button in the top left corner of the main window
  4. In the composer, manually type an email address not in the contacts list (e.g. foo@bar.com)
  5. Press tab or click on another field of the composer
  6. The warning message appears

Actual results:

A warning message pops up at the bottom of the composer saying "The 291 recipiens in To and Cc will see each other's address. You can avoid disclosing recipients by using Bcc instead"

As a user, this makes me concerned that Thunderbird might accidentally send my emails to other people and erodes my trust in the product.

Expected results:

No warning should have appeared since I'm sending a message to a single recipient.

Did you create a list with that name?
Can you reproduce with Help | Troubleshoot mode (add-ons disabled)?

I did not create a list with that name, it is reproducible with every (real or dummy) address I type in the To field. I tried with 'foo@bar.com', 'foob@ar.com' and other variations.

I restarted Thunderbird in Troubleshoot mode and could reproduce again.

I have no idea how that could happen.

Summary: Typing an email address manually in the 'To' field triggers a warning message → Typing an email address manually in the 'To' field triggers a warning message (public-recipients-notice-multi)

Happy to sit in a call or send debug logs if there's such a mechanism.

It's a fresh install of Thunderbird of macOS, but there might be data leftovers from an older install from the early days of Supernova.

Can you try with a new profile? From terminal start with the -p switch (or through Help | Troubleshooting information, about:profiles)
Also try re-installing Thunderbird.

The same thing happens when trying with a new profile created from about:profiles

I tried removing the app from the Applications folder, downloading a fresh dmg from thunderbird.net and reinstalling it. I can still reproduce.

I have no idea how that could happen.

Some broken auto-CC configured in the account settings?
