Hi everyone,
We just released some changes to our FIDO U2F implementation and it should now work with any browser that implements the window.u2f API (Firefox 57+) or implements the Chrome U2F plugin (Chrome & Opera).
Please note, U2F has not been publicly released in Firefox and requires turning on the security.webauth.u2f config flag in about:config in order to take advantage of the functionality. Since this is currently behind a flag in Firefox, you should assume it is beta functionality and you may encounter bugs or other issues that may need to be fixed by the Firefox team.
Thanks!
