Thunderbird Community Forum

I have a valid x.509 certificate and am able to send S/MIME signed emails via Thunderbird 128.5.1esr (64-bit) [Windows 10.0.22631.4460).

The private key is stored on a Yubikey. However, the certifying authorities are in the Thunderbird Authorities.

I can send S/MIME signed emails.

Viewing the received email in Gmail (web) correctly shows that email is signed, verified by a known issuer, and provides links to the certificates.

Viewing the same received email in Thunderbird only shows the S/MIME badge/icon when the Yubikey is connected.

Is this intentional behavior? Why doesn't Thunderbird show the S/MIME badge?

Remote content notification bar has disappeared and I can not access content I wish to see. How can I get it back without specifying individual email accounts? In other words I liked to be offered the choice each time remote content is blocked.

How to set a password to open Thunderbird?

I just installed Thunderbird 115.16.0esr (64-bit) on Ubuntu 24.04.5 LTS and it is working with the email I linked it.

I wanted to set a password to open TB because it is enough to click and it access the linked email.

I tried startupmaster-1.6.5-fx+tb.xpi but when trying to open it firefox says "corrupted file"

I don't like master password, I type passwords myself

Any clue?

thanks
