Hi there, im a 'newbie' as such, as i haven't touched linux in a good 3-4 years and have forgotten a fair bit... We have a fedora core 4 workstation connected to our network here, but we can't get to the internet (using firefox) not sure what we've gotten wrong (we can get our internal sites oncampus, but once we go offcampus (i.e. google.com) normally we get asked for a squid proxy prompt to put our usernames and passwords in to access the actual internet, we've added the settings in the same way we have on all the macs and windows machines here with firefox, no luck unfortunately.

I checked the firewall settings, and have allowed http and https to come through.

is it something we may have missed? (probably :P)

http: 80
https: 443
proxy: 8080

Or whatever the admin set it as. Allow that port through.

is that under the console typing setup then firewall configurations? or is there a conf file for that kinda thing?

In KDE it is under the start menu > system settings > security level. If the proxy service is issuing a 8080 challenge response, your firewall may be blocking it. If you initiated a 8080 connect- and the server accepted it, then it wouldn't matter. But, from what you describe, it actively prompts you. So, yea, you may be blocking it from incoming.

A smarter admin would do a transparent proxy and block ip subnet access for those who should do without. Unless he likes the attention he gets from helpdesk calls. Sounds a bit old school, but what do I know.
