Option Enabling Tell websites not to sell or share my data

[FrittenLoverMarvin]

What do you think about adding an option to enable the feature Tell websites not to sell or share my data?
I suppose it may be similar to Send websites a "Do Not Track" request which is already possible.

Thanks for this awesome tool. 👍

Yes, it should be added. Many sites may ignore it, but maybe some respect it and it could have legal implications in the future.

Setting: privacy.globalprivacycontrol.enabled
Possibly also: privacy.globalprivacycontrol.pbmode.enabled (the default is already true)
