To bypass a blocked server you'll need to know what method was used to block you. So your first step is to ask the webmaster or administrator who blocked you how he did it and how to circumvent it.
To open facebook: go to www.facebook.com in your browser.
How to install software on a website depends on the server OS and the server tools used. And, of course, you need access rights. For both the current administrator is the only source to get that information.
