If you don’t like the idea of online companies watching every move you make on the web, you may want to watch for Mozilla's new Non tracking system for Firefox. Mozilla announced its Web browser will be the first to answer the FTC's request for a do-not-track system.
There is one thing I would point out though. Don't be fooled into thinking this automatically stops you from being tracked while browsing. In order for the browser's do-not-track feature to work, tracking companies must first agree to stop monitoring users who have enabled the feature.
As a user of firefox, I am glad this web browser is considering to offer this service. No other web browsers are offering it. The companies with the biggest Web browsers, Microsoft and Google, have tons of online ad businesses that uses online tracking. Firefox doesn’t have its own ad business, but it gets most of its funding from an advertising arrangement with Google.
It is easy to recognize that browsers with advertisers do not want to create a system that would automatically lock out their advertisers. If they don't want to loose advertisers, their only choice is to offer this suggestion to the advertisers that you do not want to be tracked. We will have to wait and see if it works.
