Firefox root CA Cert Import
I'm trying to import a CA cert on Firefox on android, there isn't a way to import the same way as on the desktop version, from settings. I've tried putting the CA Cert on a website and downloading it, I've read that using this method Firefox would recognize that it is a CA cert, and offer to install it. I've also tried using the file:///path/to/ca/cert.crt but it just opens it as a text file.
how can I import a CA cert file on Firefox Android? is there an add-on, or ADB command? a way with root on android? a separate app to import it? How is this done?
