your probelm can be solved using ultrasoft software (i think) you can download it frm ultrareach.com or search it on google,this software takes you to the site in hidden form so server cannot detect facebook is being open,but I dont know much abt internally of the software download ultrasoft,run it and open any of blocked site,but this software slows the internet speed as site goes through it,but if it is engough for you with that speed u can use it.
just run the software and run the site in internet explorer as it works only with internet exlorer.
