Hello,

I had issue to verify the cert on android app for https://partners-enrichment.heytelecom.be. On Windows I didn't have the same issue.

version 144.0.2 / build id 20251027123126 / target arm64-v8a armeabi-v7a x86_64 Device: Samsung S22 / One UI 7.0 / Android version 15 / version S901U1UES8FYI2 / Security patch level September 1, 2025

Error: Secure Connection Failed, because its certificate issuer is unknown, the certificate is self-signed, or the server is not sending the correct intermediate certificates.

CertChain RCA: DigiCert Global Root G2 DCA: DigiCert Global G2 TLS RSA SHA256 2020 CA1 cert: partners-enrichment.heytelecom.be

1) I couldn't check the cert from the gui as on windows. Shield in search bar / Connection not secure doesn't opened the cert. Is it expected?

2) I found this helppage: https://support.mozilla.org/en-US/kb/setting-certificate-authorities-firefox

Unfortunately about:preferences isn't available on android (ref. https://www.reddit.com/r/firefox/comments/u593x0/how_to_access_to_aboutpreferences_on_android/)

I see in about:certificate which is the correct RCA (I verified the pem file with the root). DigiCert Global Root G2

Where do I check the Intermediate CA's (DCA)?

3) When exporting the RCA it has been download as: digicert-global-root-g2.pem.txt Why the txt at the end?

On Windows it downloads as digicert-global-root-g2.pem

Kind regards,

I installed Thunderbird a few days ago and it worked fine for about 12 hours and then I got repeated messages saying "certificate error" and that the app detected potential security threats. After that, I could no longer access my emails. My email provider is Telia, a company in Sweden, which is where I live. I called Telia but they say the problem is on your side. They are not aware of any security threats.

Here is a screenshot of the warning.

Should I go to the advanced settings and say I accept the risk and just continue?

Thanks in advance. Barbara R, Sweden

State of Thunderbird's OpenPGP support?

When I export my private key and add more user IDs to it, GPG adds extra feature flags that apparently aren't supported in Thunderbird. I've tried following the directions here, but GPG doesn't seem to do anything different with the --rfc4880 flag, and so importing the key back into Thunderbird still gets the "unsupported features" warning.

Even when creating a key in Sequoia-PGP, it seems to add an extra notation? And that also seems to make Thunderbird say it's an extra unsupported feature.

Am I doing something wrong?
