This is a fork of https://ipv.sx/u2f/ that uses the U2F JS API v1.1

To use this to test U2F support in Firefox using its built-in software token, do the following:

1. Open the Firefox advanced preferences in about:config.
2. Search for "webauth"
3. Enable (value=True) these two:
   • security.webauth.u2f
   • security.webauth.u2f_enable_softtoken
4. Reload this page and click buttons!
