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.

Hello, I am running Firefox on a W10-Pro PC. I always click the lock to check certificate validation. In the last month I keep seeing "Connection verified by a certificate issuer that is not recognized by Mozilla".

When I click for more information I see that "Norton Web/Mail Shield" does not recognize the certificate issuer. When I click on Learn More it takes me to a Firefox site "How to disable the Enterprise Roots preference" I also checked W10 certmgr.msc and I see Norton is listed. Images included below. I would love to resolve this issue. Thank you for your time.

I start firefox with following policies.json

{

   "policies": {
       "AppAutoUpdate": false,
       "BackgroundAppUpdate": false,
       "DisableAppUpdate": true,
       "DisableFeedbackCommands": true,
       "DisableFirefoxAccounts": true,
       "DisableFirefoxStudies": true,
       "DisablePocket": true,
       "DisableSystemAddonUpdate": true,
       "DisableTelemetry": true,
       "ExtensionUpdate": false
   }

}

But uncontrolled connections to the following addresses continue anyway:

• firefox.settings.services.mozilla.com
• aus5.mozilla.org

I may have missed something and you can tell me how I can control these connections inclusive. Because all other connections can be controlled by configs and policies. But not these and it raises big questions. It seems to me that the browser should allow to configure any network requests that aren't related to the user web browsing itself. If some connections cannot be controlled in any way then I can't call it anything other than either a bug or an attempt to monitor users as do in Google Chrome.

Is it possible with the iOS app (128.3) to view values of cookies stored for a website? It doesn’t appear as though that is data that can be synced to desktop, either. (Would make sense for some browser-specific key:value) If it helps, I know the name of the cookie I’m specifically looking for.

Bonjour Madame Monsieur, Afin d'utiliser Firefox je désire connaître vos conditions de confidentialités pour ne pas avoir de phishing. Car j'ai déjà été victime d'usurpations de données personnelles. Merci

I keep getting pop-ups in the right lower corner from "mozilla firefox" (not sure if they are legit). They will say: "zeus.2020 trojan detected" or "virus detected" or "system is infected", etc. All have "Mozilla Firefox" in the upper left of the pop-up, and "via rgfirewall.xyz" at the bottom. Is this truly legit, or is it just a nuisance? I've just been closing them with the x or dismiss buttons.

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

Currently, I am using the desktop version of Thunderbird and I have my email account configured to digitally sign my emails with an S/MIME certificate. I cannot find a way to import my certificates on the android version of Thunderbird. Is there away to setup certificates in the Android version of the app?
