Introduced in Firefox version 120, you can make use of Global Privacy Control (GPC) to automatically notify websites not to sell or share information about your browsing session on that website.
GPC operates as a “Do Not Sell” mechanism in some US states such as California, Colorado and Connecticut.
It may also be used to indicate an opt-out of targeted advertising or general request to limit the sale or sharing of your personal data in those jurisdictions, as well as in jurisdictions such as the EU, UK, Nevada, Utah and Virginia.
Mozilla added this feature to give you more choice and control. If you’d rather not send the signal, you can turn it off anytime.

Frequently asked questions
Does this stop all tracking?
No. GPC only sends a request signal. Some websites may still track you.
Can websites ignore GPC?
Yes. Outside certain regions, compliance is optional.
Does GPC replace Do Not Track?
No. GPC is newer and has stronger recognition in laws like the CCPA and GDPR, but both features can be used.
Will enabling this break websites?
Usually no. It just sends a privacy signal. If you notice issues, you can turn it off.
