Google has an extension called “Keep My Opt-Outs” available for Chrome browser users that will block all cookies related to personalized ads. The cookies in question track a user’s path across various websites and then use that history to serve relevant advertisements. Web browsers all include a setting to block this process but a number of advertisers such as Google use a special code to circumvent this setting in browsers like Safari and Internet Explorer.
“Keep My Opt-Outs is an extension for users who are not comfortable with personalization of the ads they see on the web,” Google noted on the extension’s Chrome Web Store page. “It’s a one-step, persistent opt-out of personalized advertising and related data tracking performed by companies adopting the industry privacy standards for online advertising.”
Keep My Opt-Outs will work on OS X and Windows computers, but only in the Chrome browser.
