Bought yubikey on a sale a few years ago. Not usable for mobile in that model (4?) (but I knew it in advance of course). Then found out that most of the sites don't accept it in the Firefox, only in the Chrome and its clones. And so it is collecting dust somewhere in my old apartment.

I had similar issues with Safari a few years ago. The situation has vastly improved as most modern sites detect for FIDO2 support instead of just scanning your browser agent.

They’ve natively worked in Firefox for a couple of years now.
