Get frustrated!! Facebook, youtube is not opening in your college. Don't Worry! Here's the solution:
- Write in address bar https://www.facebook.com instead of http://www.facebook.com
- On every next page, replace http:// with https:// or enable secure browsing from Account settings.
- It's Working in my college. I am not sure about all colleges, but it will work in most of colleges because they mostly block facebook, youtube from port 80 not from 443 i.e. https.
Note: If this trick does not work, then try ultrasurf, tor browser or some other proxy sites.
