Twitter is the latest site to jump on the Do Not Track bandwagon. The privacy feature, which is currently in use in several major browsers including Mozilla's Firefox, allows users to opt-out of third-party tracking.

The Federal Trade Commission's chief technology officer Ed Felten revealed the news this morning during an Internet Week privacy panel and Twitter confirmed the announcement in a tweet.

Mozilla, who hosted the Do Not Track event, shared its excitement for Twitter's support in a blog post. According to the post, 8.6 percent of Firefox desktop users have adopted Do Not Track, while the feature has attracted more than double the amount of mobile users, at 19 percent.

As advertising becomes more personal, focusing on age, gender and interests, social networking sites in particular have been known to provide advertisers with user's information to tailor fit ad experiences. Facebook has probably done this to the largest degree, though Twitter has also forked over some user data in the past.

But with its recent actions, including its court motion in favor of protecting the tweets of an Occupy protestor, Twitter has shown its interest in supporting and defending its users.

When enabled, Do Not Track informs websites and advertisers that users do not want to be tracked for purposes such as behavioral advertising by allowing users to opt-out of cookies that collect personal information. Users can turn on the feature in their Internet browser's privacy settings, and sites, such as Twitter, will prevent users from being tracked in any way while browsing.

Other websites that have voiced their approval of Do Not Track include AOL (The Huffington Post's parent company), Google, Microsoft and Yahoo.

Microsoft's Internet Explorer was the first to comply with FTC demands last year when it released the Do Not Track option. Firefox joined the crusade shortly after, and other major browsers have since jumped on board.

Apple's Safari includes the feature in its soon-to-be released 5.2 version, while Google has plans to add the feature to Chrome later this year -- a preliminary extension is available for web surfers to try out the feature now. For Opera users, Do Not Track will be available in its Opera 12 browser release.

    If you're angry at your boss or playing hookey from work, you probably shouldn't tweet about it. Furthermore, warns Amber Yoo of <a href="http://www.privacyrights.org/" target="_hplink">PrivacyRights.org</a>, tweeting your opinions about work-related topics can lead to trouble in-office. "Unless they are glowing, don't Tweet opinions about your company, clients, products and services. Employers are increasingly monitoring employee conduct on Twitter," says Yoo.

  • Geotagged Photos

    It's a risky move to tweet photos that show what you look like and what your home looks like. Including geotags with these types of photos could put you at risk.

According to <a href="http://www.privacyrights.org/geotagging-privacy" target="_hplink">PrivacyRights.org</a>, "Your real-time location may indicate your home and work addresses, your commuting patterns, what religious institution you visit, how often you go to a doctor, political rallies you attend or whether you are seeking the advice of a lawyer."

  • Racy Or Inappropriate Photos

    "Employers routinely check out Twitter prior to hiring an individual, and have referenced social networking as helping them make choices on future employees," says <a href="http://www.reputation.com/" target="_hplink">Reputation.com</a> founder Michael Fertik. "Use better than average common sense when uploading photos to Twitter - if you wouldn't want your boss or grandmother to see it, it's probably a good idea to hold tight and keep it offline."
