Tried but it has now been "upgraded" to the stables manner of working (e.g. loading until infinity).

It would be nice to have basic ssl support like client certificate authentication seeing as this is currently broken for at least 10 months with someone (can't verify whether he is part of dev team or not) that is has priority but after 10 months no results and the "stable" version that just keeps loading forever and the beta just giving up and acts like the certificate is not installed seems a little ridiculous.

please get this sorted as I do not feel like looking for a new browser again.

So here we are nearly a year later and still no client certificate support? Are your developers actually try to build a decent usable browser as the rest seems all seem to have figured this out several years ago (yes I did check to make sure chrome actually has this working since you are using the same engine).

do fix this or I will have to look at different browsers AGAIN but this is basic functionality and used more or less everyday.
