Most of the work places, institute, college, university etc... block certain sites, usually they block the access to social networking  and entertainment sites. There are many tricks to overcome this issue, but I am going to show you a simple trick to enjoy certain blocked sites (Facebook, Twitter, Google+, and YouTube) from your institute or work place.






How to do it?
System administrators block only http://, but not https:// , so you can simply add the letter “s” after http and access into that particular site.

For example:
Change http://youtube.com/ into https://youtube.com/ , so you can try in any place where your blocked site lets you enter through the secure protocol.

 This trick is working well in Mozilla Firefox, I don't know it will work in other browsers or not.
