Hello, The default browser in our company is Firefox. We have some internal websites now available from outside with mTLS. This is working fine with Firefox on laptop (fedora), but I cannot make it work with Firefox on Android (which is crucial as the aim of this project is to have those apps securely available to all or employees from outside). I installed the user certificate in the Android "User credentials" trust store, but Firefox (version 128.0.1) is not offering to use that certificate for mTLS, and just show a "Secure Connection Failed" error message. How can we have Firefox on Android using the user CA to access those applications? Thank you in advance for your feedback. Best regards, B.
