How to prevent websites from tracking your data?

Let me explain first what exactly web tracking is. Normally, when you visit a website-let it be any type of website- your web behavior is tracked by the websites for the purpose of showing you relevant advertisements. A tracker has the ability to learn about the name of the sites you visit, the things you like or dislike. Firefox has an option to tell the websites not to track you. Remember that every website may not honor your tracking settings, which means that despite requesting the site not to track your information, the website may ignore your request and keep tracking your web behavior.  But, the good news is most of the high profile websites honor these non-tracking settings and will not track you if you set the tracking off. To turn off tracking from Firefox, you have to click the privacy tab on the option menu and then check “tell the websites that I do not want to be tracked”.

Use NoScript Extension

This NoScript extension prevents cross site scripting(XSS) and Clickjacking attacks. It allows you to choose the websites that you want to permit to run active contents(Java, JavaScripts etc) in your browser.this is a must use addon for your Firefox.
