Geek Posted April 16, 2011 Posted April 16, 2011 <div class="KonaBody"><p><img src="http://osxdaily.com/wp-content/uploads/2011/04/safari-lion-do-not-track.jpg" alt="Safari Lion Do Not Track HTTP Header " title="safari-lion-do-not-track" width="620" height="332" class="aligncenter size-full wp-image-15027" /></p> <p><strong>Note:</strong> This feature is currently only in Lion Dev Previews, but it will likely come to a Safari update for existing versions of Mac OS X in the near future.</p> <p>Safari 5.1 in <a href="http://osxdaily.com/tag/mac-os-x-10-7/">Mac OS X Lion</a> Developer Preview 2 has added a new feature that blocks cookie tracking used by online marketers. Cookie tracking may sound more nefarious than it is, because the general goal of tracking your web activity is to serve the most relevant ads to you. This is why when you look for a product online and check out that products web site, suddenly advertisements for that product are appearing elsewhere on the web afterwards.</p> <p>Personally, I’d rather have ads that are geared towards me and things I’m interested in than some of the generic and annoying advertising out there. Show me ads for Apple products, not ads for generic Windows virus and Registry scan crapware, and this is the kind of ad targeting cookie tracking enables. I’ll elaborate more on this later, but nonetheless, I think the more control you have over your browsing activities the better, so I’m happy to see the do-not-track option appear in upcoming versions of Safari. </p> <p>Enough rambling, here’s how to enable this feature in the current Dev Preview: <span id="more-15026"></span></p> <h2 style="font-size:1.2em;">Enabling “Do Not Track” in Lion’s Dev Preview Safari 5.1</h2> <p>You’ll need to turn on the Safari Develop menu item first:</p> <ul> <li>Open Safari Preferences from the Safari menu</li> <li>Click on “Advanced”</li> <li>Select the checkbox next to “Show Develop menu in menu bar”</li> </ul> <p>Now that the Develop menu is enabled, you can select the Do Not Track feature:</p> <ul> <li>From the Develop menu, select “Send Do Not Track HTTP Header”</li> </ul> <p>Changes seem to take effect immediately but you should <a href="http://osxdaily.com/2009/12/10/clear-cookies-in-safari-on-a-mac/">clear your Safari Cookies first</a> to really see the difference.</p> <p><strong>Results of Do-Not-Track: The Good, The Bad, The Annoying, and The Reality</strong> I finally got a chance to try this out after seeing the feature mentioned a few days ago on <a href="http://www.macgasm.net/2011/04/13/apple-adds-track-support-lion/">MacGasm</a>, and the good news is that it works as you’d expect. With the Do Not Track HTTP Headers enabled, the advertising presented to me across the web was much more generic and I no longer had ads that were geared towards me based on cookie tracking. Here’s the bad news, yes you gain some anonymity, but you also gain a barrage of generic Windows registry/virus/just-buy-a-freaking-mac-save-yourself-the-headache-of-this-rubbish scammy crapware ads again, amongst some other completely random annoying advertising. After seeing all of this, believe it or not, I quickly missed my cookie-targeted ads for things I’m interested in and use, like Mac Mini colocation, ZAGG iPhone Shields, Apple products, and software I use. For me, this proved that not all cookie tracking is bad, and I actually disabled the Do Not Track feature. The reality is that online advertising supports virtually all websites, including this one, so if I’m going to support sites I like and see ads, at least show me something relevant.</p> <p><strong>Do Not Track Isn’t Enough For You? Here’s How To Get Even More Web Privacy</strong> I realize not everyone is going to share my opinion on ad relevancy and cookie tracking. If you’re really paranoid about online tracking and want the ultimate in web browsing privacy on a local machine without using an anonymizing proxy, you’ll want to go further than just using these do-not-track features. Combine do-not-track alongside with <a href="http://osxdaily.com/2007/02/09/private-browsing-little-known-safari-feature/">Private Browsing in Safari</a>, then install some ad blockers, <a href="http://osxdaily.com/2009/09/24/stop-flash-from-automatically-loading-with-clicktoflash/">use ClickToFlash</a>, or better yet, <a href="http://osxdaily.com/2011/01/09/uninstall-flash-mac/">uninstall Flash completely</a> and <a href="http://osxdaily.com/2009/11/13/delete-flash-cookies/">delete your Flash cookies</a> to prevent Flash ads from following you around too. There’s even more you can do, but that’s a start.</p> <p>Happy browsing!</p> </div> <p><a href="http://feedads.g.doubleclick.net/~a/Qx68wb4zhOUr8N1RTY7NIp2lB48/0/da"><img src="http://feedads.g.doubleclick.net/~a/Qx68wb4zhOUr8N1RTY7NIp2lB48/0/di" border="0" ismap="true"></img></a><br/> <a href="http://feedads.g.doubleclick.net/~a/Qx68wb4zhOUr8N1RTY7NIp2lB48/1/da"><img src="http://feedads.g.doubleclick.net/~a/Qx68wb4zhOUr8N1RTY7NIp2lB48/1/di" border="0" ismap="true"></img></a></p><div class="feedflare"> <a href="http://feeds.feedburner.com/~ff/osxdaily?a=3yahIBO074o:iXXlQSlkElw:yIl2AUoC8zA"><img src="http://feeds.feedburner.com/~ff/osxdaily?d=yIl2AUoC8zA" border="0"></img></a> <a href="http://feeds.feedburner.com/~ff/osxdaily?a=3yahIBO074o:iXXlQSlkElw:V_sGLiPBpWU"><img src="http://feeds.feedburner.com/~ff/osxdaily?i=3yahIBO074o:iXXlQSlkElw:V_sGLiPBpWU" border="0"></img></a> <a href="http://feeds.feedburner.com/~ff/osxdaily?a=3yahIBO074o:iXXlQSlkElw:D7DqB2pKExk"><img src="http://feeds.feedburner.com/~ff/osxdaily?i=3yahIBO074o:iXXlQSlkElw:D7DqB2pKExk" border="0"></img></a> <a href="http://feeds.feedburner.com/~ff/osxdaily?a=3yahIBO074o:iXXlQSlkElw:7Q72WNTAKBA"><img src="http://feeds.feedburner.com/~ff/osxdaily?d=7Q72WNTAKBA" border="0"></img></a> <a href="http://feeds.feedburner.com/~ff/osxdaily?a=3yahIBO074o:iXXlQSlkElw:qj6IDK7rITs"><img src="http://feeds.feedburner.com/~ff/osxdaily?d=qj6IDK7rITs" border="0"></img></a> </div><img src="http://feeds.feedburner.com/~r/osxdaily/~4/3yahIBO074o" height="1" width="1"/> View the full article
