Protect your privacy with NoScript Firefox plugin
Many people complain about issues with their privacy, much to do with information being stored when browsing to when using a social network. Part of why we are able to access so many sites freely is due to the fact that they can take our information.
To a certain extent this is okay as long as we are aware of what they are taking and to whom they are giving that information to, which you can check easily through PrivacyFix (another plugin), however, revoking such info does not give them another alternative to provide you with a free service, which causes an unbalanced medium.
