Since getting our M1 iMac set up, when my wife is on Firefox on the iMac, there's a Firefox icon next to the dock of my 2012 MBP. It's not in the dock per se, but adjacent with its own dock background. Clicking on it, I can see what web page she's on, but not what's happening with the mouse or keyboard. I updated FF on the MBP around the same time. WTH is it?

You mean the Handoff icon?
