Where are you getting this certificate from? And whom you got this from should've given instructions on how to install their certificate on Firefox.

In current releases it is:

• Settings -> Privacy & Security -> Certificates -> View Certificates

That's to _view_ the certificates. How does one _install certificates? ~ahh - there is a scroll bar to the right hiding those options. Smart.

What kind of certificates do you want to install as there is normally no need to install root or intermediate certificates under "Authorities" except for special cases under "Your Certificates"?
