Right, those are the same symptoms as yesterday. Like we discussed, it is your SSL certificate that is using a weaker SHA-1 algorithm causing FireFox and Opera to reject the certificate. If you say your using SHA-256 now, then you should post any error messages you are getting from FireFox console here.
Also, you don’t need to use betaui as the issue is unrelated. Therefore, you can continue using: https://ui.opensprinkler.com/js.
