Have recently been review my privacy settings in more detail and have stumbled upon the following via Privacy & Security>View Certificates>Servers

Can anyone please explain to me in idiots terminology what these are, what they do, and should I keep or delete them?

I suggest you leave them in as if deleted you cut your connection to the web off as they are needed to talk/make requests to other servers. https://support.mozilla.org/en-US/kb/secure-website-certificate

Please let us know if this solved your issue or if need further assistance.

Thanks! So the x3 certifcates on my screenshot are okay? I've read that the cm9.net server relates to sky broadband hubs & routers? I cancelled that service several years back so wondered what it was...

Your screenshot shows permanent block exceptions on the Server tab for certificates that shouldn't be trusted anymore. You shouldn't remove these exceptions.
