When looking in my list of “Synced tabs” I see the devices I should do with the correct synced tabs. However, I also see an old device that I no longer use, and is no longer connected to Firefox. However, when I go into my account to see the list of devices, it is not listed, so I cannot remove it. I have signed out all of my devices, restarted and updated everything, but it is still there and I can see it on the synced tabs on all of my devices, yet not in the device list of my Firefox account. Is there some way to remove this old device - I’m pretty sure it’s just showing up as a bug and by clearing or resetting some cache it will go away. Any ideas?
