Firefox cannot verify applet signature

[Jarl]

Binary package hint: firefox-3.5

I tried to visit my netbank. They have apparantly signed their applet with a new certificate. So I got the warning saying "The application's digital signature cannot be verified".

I also tried the same thing in firefox on windows and did not get this warning.

To reproduce just enter https://www.netbank.nordea.dk/netbank/index.jsp

I visited the page in this bug's description using Firefox 53.0 on Ubuntu 17.04 "Zesty Zapus" and did not receive any error.
