Starting in Firefox version 135, the “Do Not Track” setting has been removed. Many sites do not respect this indication of a person's privacy preferences and, in some cases, it can reduce privacy. If you wish to ask websites to respect your privacy, you can use the “Tell websites not to sell or share my data” setting built on top of the Global Privacy Control (GPC) feature. GPC is respected by increasing numbers of sites and enforced with legislation in some regions. To learn more, please read Global Privacy Control.
