That is my understanding as well. I haven't been able to get my U2F working on recent Firefox builds. It's such a shame because I really want to use U2F instead of an authenticator app. I have like 20 different sites in there and finding the right number always takes me a minute or two.

Also Google Hangouts and Meet do not work.

Google literally checks for Chrome >_<

On GitHub, U2F works with the Firefox addon https://addons.mozilla.org/en-US/firefox/addon/u2f-support-a...
