How to block third-party cookies in Chrome, Firefox and IE browsers

Mozilla has decided that starting with Firefox 22, the browser will not allow third-party cookies to be installed on the user’s computer if the user has not visited that website. If you don’t want to allow third-party cookies on browsers like Google Chrome, Firefox, and Internet Explorer by default, here’s how to do that.

Let me tell you about third-party cookies with an example: when you visit a blog that has sharing buttons placed below the post, those buttons may track you by installing cookies on your computer that Facebook and Twitter can read, they are called third party cookies. Here you have not visited these sites directly.
