Mozilla Firefox to block tracking tools in its new version

Mozilla has released a pre-beta version of Firefox whose updated, experimental Private Browsing mode blocks web elements that could track the user's behavior, such as analytic tools and social network services. According to the Engadget, this measure could break some sites. Mozilla feels that it is ultimately better to keep the users off sites' radars by default.

If the users run into problems, there is a central control area where they can change their privacy and security settings. Also, it enforces add-on verification by default so that social plug-in the users downloaded should not add unwanted toolbars, inject ads or collect more data than it should. The users can turn off this filter.
