How do I disable the Insecure password warning?

Hi,

I was doing an online CTF challenge that uses an http server and doesn't work with https. The challenge features a fake login prompt and firefox keeps showing me the "This site is not secure" warning when I try to type a password, which is distracting and completely useless here because I'm not sharing any private info on that site.

I tried [post] but it didn't work btw.

You'll need to ignore it, or tap the Esc key to dismiss it. The old preference to hide it was removed.
