To enable Global Privacy Control (GPC), use web browsers that already have built-in the GPC signal, like Firefox Nightly, Brave, and DuckDuckGo; or download browser plugins for GPC, including Abine, Disconnect, and OptMeowt by privacy-tech-lab, and Privacy Badger by the Electronic Frontier Foundation. To make sure GPC is turned on, check it at https://globalprivacycontrol.org/.
