Yeah, what jlinkels said...
If I can re-phrase your question correctly, you wish to translate arbitrary web pages containing functionality that can only be achieved with plugins and graphical elements, into something that can be rendered on a text-only console. I would have to wonder why a developer would have used such plugins, if the same functionality could be achieved without them. Moreover, much of the functionality in a site such as facebook is achieved by server-side code, and you cannot simply download this code.
I would rate your prospect for success in this endeavor as somewhere less than 4/5 * sqrt( zip );
