Mozilla on Tuesday released the latest beta version of its Firefox 4 browser, which includes a "do not track" option.
"With the integration of the 'Do Not Track' option into Firefox 4 Beta, you can now check a 'Do Not Track' box in the 'Advanced' screen of Firefox's Options," Mozilla said in a blog post. "When this option is selected, a header will be sent signaling to websites that you wish to opt-out of online behavioral tracking. You will not notice any difference in your browsing experience until sites and advertisers start responding to the header."
Mozilla added the feature to a pre-build version of Firefox late last month. The company also discussed plans for a "do not track" feature the week before.
Mozilla is not the only browser maker considering this option. The concept made headlines in December when the Federal Trade Commission unveiled a broad plan for online privacy, which included the "do not track" provision. Days later, Microsoft announced that its next-generation Web browser will include a privacy feature called Tracking Protection, which will give users control over which sites can send and receive data from their browser. Google recently announced a Chrome extension called Keep My Opt-Outs, which empowers users to permanently opt out of ad-tracking cookies.
