AdSense Publishers Wonder If "Keep My Opt-Outs" Will Hurt Earnings

Today Google’s Chrome browser announced an extension called “Keep My Opt-Outs”. This extension allows the user to opt out permanently from all ad tracking cookies. The Google announcement added:”We’re working to make this feature available for other browsers, too. We’ve also decided to make the code for this extension available on an open-source basis, so that other developers can let us know if there’s a bug, or even extend the code’s capabilities if they want to.”
