I am using WSO2 IS 5.3.
I integrated it with U2F.
When I use it in authentication, it give me a blank page (https://localhost:9443/authenticationendpoint/fido-auth.jsp) but when I use it with previous version its work well!
What is the problem between the last version and Fido token ?
And why the fido token works just with (google-chrome) not (Firefox) ?
