Import CA certificates
I am being dumb ! - how do I import a CA certificate into Vivaldi ?
And is it possible to add one for every user of the machine so each
user doesn't have too
You did not tell about your Linux.
You need to install certutil from libnss3-tools.
And read http://blog.avirtualhome.com/adding-ssl-certificates-to-google-chrome-linux-ubuntu/ and https://wiki.archlinux.org/index.php/Chromium/Tips_and_tricks#SSL_certificates how to install your own local CA certs.
Please feel free to ask.
Sorry - openSUSE Leap 42.2
@interele Did it work in OpenSuSE shell with certutil?
