I have two computers, one for personal use and one for business. Somehow the tabs between the two computers are being shared and I cannot disable it. Both browsers are signed into different Firefox accounts, Sync is turned off on both, and there are no connected devices. Yet despite that, when I go to one computer, it pops up a Firefox icon (see attached) in the taskbar that lets me open the tab open on the other computer. This is incredibly frustrating and Firefox should not automatically share this information, and should not make it so difficult to disable.
