It's a cookie that applies across all browsers and devices, and you cannot remove it. There is no way to opt-out of this tracking. Analytics and ad operators, social media firms, and other data exchanges can identify you using this, and they can use this information for tracking what you say and do online. Verizon has been in business with these companies to sell your identity to them -- Verizon is effectively including your name, address, Facebook account, and email address with every HTTP request you make. Again, this applies across all browsers and devices, and you cannot opt-out.
