Nope, whatever they had me download. It's Macs so maybe they autoattached to handover or whatever Apple calls that feature. Which I like, but only for texts and phone calls.

The devices I mention are all in the same local network so maybe they discover each other.

Anyway, there's a post in this thread that explains perfectly why I (or that poster) don't need or want sync. Basically my different machines are used for different purposes so there's no reason to mix bookmarks or move browsing history around. As for credit card numbers... what is this insanity? I don't save credit card numbers anywhere.

It’s probably handoff. On chrome I get the extra icon as well, but it also has a phone mini-icon over it and a tooltip saying “from Safari”. You can disable handoff, just goo—er, duckduckgo it

I wonder if i can disable it for all apps but still keep it for calls and texts…

Call answering from my laptop is the only thing that ever made me rush out and buy a new iPhone that supported it :)

... but what's it doing in handoff without being told to do so?

Oh, Firefox on the Mac is a wild and badly understood beast. It's worse on iOS.

I have no idea what you are supposed to expect there.
