help.mojang.com certificate is no longer valid

The certificate for https://help.mojang.com/ doesn't seem to be valid anymore.

When trying to connect to that website, Firefox shows the following error message:

No connection attempt made: Possible security problem

Firefox Developer Edition has detected a potential security risk and therefore has not accessed help.mojang.com because the site requires an encrypted connection.

What can you do about this?

help.mojang.com uses a security technology called HTTP Strict Transport Security (HSTS), which requires Firefox Developer Edition to connect to the website only through secure connections. Therefore, no exception can be added for the website.

Most likely, the problem is caused by the website and there is nothing you can do about it. You can notify the site administrator about the problem.
