codeblocks forums page with firefox

[winnie]

Under ubuntu 18.04 with firefox 74.0 when I try to open a post in the forum pages I get the error that I have attached.
Now I am using Chromium but it's strange the it doesn't work with firefox. This problem started some months ago.

Firefox is (probably) forcing you to go to https and this site doesn't support this.

But I'm on ff 74 and it works fine.
