Having a problem with a Firefox Certificate warning

I have Clarkconnecr installed as a storage server, I'm new to the program and have changed so many settings I decided to reinstall. That went fine but now I'm trying to access the webgui with Mozilla Firefox and I'm getting a message saying I have recieved an invalid cetificate, I can still access it through Internet Explorer but there is a cert warning at the top of the page. How can I access it through Firefox again?

Have you tried going into the Tools|options|Encryption
and under viewing certificates, delete it and import the valid one

or just delete it and set your options to general prompt and see what is going on

You can also set yourself to not verify

Don't know if any of this works.
