html5test.com is not working for me on Firefox browser for Windows and for Android too. When i open the site, it doesn't show any result. I have the latest versions of Firefox on both devices. Two weeks ago I did the same thing and it went very well

I see the same issue.

If I check the Web Console then this looks like being caused by an expired certificate when requesting this file:

GET https://api.whichbrowser.net/rel/detect.js?ua=Mozilla%2F5.0%20(X11%3B%20Linux%20i686%3B%20rv%3A79.0)%20Gecko%2F20100101%20Firefox%2F79.0&e=24&f=95&r=a25ommg&w=1173&h=939

[HTTP/1.1 200 OK 22ms]

Connection:	
Protocol version:	"TLSv1.2"
Cipher suite:	"TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256"
Period of Validity	
Begins On:	"May 7, 2020"
Expires On:	"August 5, 2020"


If I open this file in a tab and override this error then Firefox loads this file from the cache.

It is working now. That means that the certificate is valid again. Thanks a lot for the answer!
