After moving from my laptop to my desktop a popup briefly appeared
apparently from Firefox saying "Pasting from <name of laptop>".

Does anyone know what that's about?

Are you synchronising the Firefoxes with the Mozilla Cloud and did you
leave by chance the laptop open with your FF running?

If you have two Macs logged into the same iCloud account and a
reasonably recent MacOS then you can cut on one and paste that content
into the other. When changing from one machine to the other you get a
brief popup alert to let you know that if you paste, it will be what you
cut on the other machine not what you last cut on this machine, IFSWIM.

I have Firefox set to sync bookmarks and nothing else. The laptop was
closed.

It could be that - it might just be coincidence that it was in the
middle of the Firefox window. And it appears to require wifi (why?),
which had somehow been turned on on my desktop, so that might explain
why it hadn't happened before.

Thanks,

But why does it require wifi rather than a wired connection?

Is it doing the AirDrop style ad-hoc wifi network between the two machines, rather than using the local network?

Yup. Using the existing well-tested security tools Airdrop already has.

I suppose that means it works in places like hotels and coffee shops, where the network might be configured for clients not to be able to talk to each other. By doing the Airdrop thing they completely bypass any limitations on the
local network. It also means the two machines need to be in physical proximity, which avoids some kinds of attacks.
