How to import a client certificate into Firefox fro Android?

I have a privately hosted website that I have secured with a client certificate.

The certificate is signed by my own Root CA, which signed an Intermediary CA that signed the various client certificates. I have created a separate certificate for each device I have.

On my different PCs I can import that certificate into the browsers certificate store and when I browse to the website, I get asked if I want to use my client certificate. If I select that, I get access to the website, without such a certificate, I just get a "403 Forbidden" page. That is how it should be. The certificates secure the sites and I don't need to enter a password.

I can get this to work with Chrome for Android, but somehow I have yet failed to find out how I can get Firefox for Android (my preferred, default browser) to work with that.

I can't find the menu in the settings (as done on the desktop version). I can install the certificate from the CA by downloading into from my website on my phone. Yet when I try that with the client certificate, it says I can't import it as it's not a CA certificate. I have tried to download different formats (cert.pem, or a PFX) but none would work.

Is this possible with Firefox for Android?

Nobody? Is that such a special request?

Hi if you have the next to last version you could probably do this easily. How ever in the latest version it is not easy. I have not tried the AdGuard method so I don't know if this will work for you Manual installation of the security certificate into the Firefox browser
