Folks, you need to TEMPORARILY allow third-party cookies to set these opt-outs because they work as cookies set by each advertiser network, telling their own network not to set any actual tracking cookies in your browser.

Once these opt-out cookies are set, you can re-block third-party cookies, in which case the opt-out won't matter anyway because you're already blocking any cookies you opted out of -- i.e., the opt-out only matters when you choose to allow third-party cookies.

This extension just makes sure those opt-out cookies don't get deleted or overridden.
