Is there a equivalent of allow-insecure-localhost flag of Google Chrome in Firefox?

Question

I want to connect "wss" (SSL-ed websocket) with insecure (self signed) cerfiticate.
But it is raise a error. This error caused by default firefox setting that it seems like does not allow connecting to self-signed ssl as well as chrome.

In Chrome, this behaivior is able to change by allow-insecure-localhost flag in chrome://flags.

Is there a equivalent flag in Firefox?

Navigate to

about:config

and look at:

network.websocket.allowInsecureFromHTTPS
