Hello, I have two mac laptops, each have Firefox (FF) installed on them. For Laptop A I am logged into my Firefox account so FF can sync with my iPhone. For Laptop B I am not logged into my FF account. Both laptops, however, are logged into my Apple ID account. When I am working on both machines at the same time I will get a second FF icon in the Docks of both machines. Clicking on Laptop A's secondary's FF icon will result in the webpage that is open on Laptop B appearing in Laptop A's instance FF. How is this happening? Is the information being passed through my Apple account? Can I disable this feature? Thanks so much. md
