How I read it is that they’ve reintroduced it in FF 139 and that you need to enable the third-party certificates to acces the client certificate in the Android cert. store. But the linked bugs in the later replies of my link mention a regression in FF 140+.
I do agree that this is still a horrible UX though. Sadly I don’t have the time currently to test it.
Interesting, I’ve never heard about that… What is the difference?
