A proxy server has nothing to do with firewalls or security at all, it is a computer (or part of a computer) which helps the internet to function, and usually speeds up your browsing. To give an example: in a school computer lab there are 50 computers. The teacher tells everyone to go to a movie site and download part of the soundtrack for an English assignment. Without a proxy server 50 identical requests go out on the schools broadband connection to the movie site. 15 minutes later people are still trying to download the soundtrack.
With a proxy server in the school, the download requests are intercepted, one
request is sent to the movie site and downloaded to the proxy server. All the other requests are loaded, at network speed, from the proxy server.
In this example the proxy server has reduced the amount of internet traffic by a factor of 50 and allowed the 50 computers in the lab to download in (close to) the same time as it would take one computer. All large organisations will benefit from a proxy server, all ISPs have them and in some cases even individuals (single PCs) use them - this is how some browser accelerators work, they use (steal?) some of your hard drive space and download everything in your favourites or most recently used list to a mini proxy-server there. When you pull up your favourite web page it comes up really fast, because it hasn't come over the internet at all - it's already on your hard drive.
EDIT: I forgot about the filtering function which I see TEEDUB2
