Who to add additional CA certificate to Fenix?

I have some webservices in my local network, which I want to secure with HTTPS. So I created my own self signed Certificate Authority and generated so some certificates for these services, signed by my CA.

My question is: How can I add the CAs certificate to the list of trusted authority certificates in my Firefox Fenix installation? I can't find such an option in the Fenix settings.

(This works well for my Firefox desktop installation, but I want to use this on my Android smartphone, too.)

Using the latest Fenix version 82.1.2.

It does not help to add the certificate to androids list of trusted CAs: Android Settings > Security & Location > Encryption & Credentials > Install from SD card


Does someone know, where "build in CAs" are stored within the APK? Maybe, I could add mine there (unzip, add, rezip the APK).


Any other idea?
