sync status out of date
I have two computers "A" and "B", side by side, both logged in to Firefox accounts.
on A, settings/clients shows J's Firefox on A current device
J's Firefox on B Last seen 4 months ago
and on B J's Firefox on B current device
J's Firefox on A Last seen 4 months ago.
They are literally 6 feet apart. Both running 84.0.1 (64-bit). Ran "Sync now" on both, "Refresh status" on both.
Make sure that sync is turned on with all devices.
