unable to play games on pch.com. Apparently firefox has a certificate problem with pch.com.

Hi,

I work in a technical profession where we have large amounts of GUI-configurable equipment. Firefox was my go-to browser to configure and maintain this equipment. Up until today, when version 140 installed unexpectedly.

There is no https in this equipment, no certificates, no certificate server, no DNS. Just a LAN cable, peer to peer, to use the browser as a GUI to manage the equipment. There is no need for high level security either, since there is no internet.

Now how do I do this? In previous versions of Firefox it was possible to override the security warning and proceed anyway, which is what we did. Now we don't get the option to override, and it does not appear there is any way to change this behavior in the settings. This heavy handed nanny stuff does not sit well with me and it has made Firefox 140 essentially useless for my purposes. I've rolled back to a previous version of Firefox for now.

Hi folks,

From time to time, the button "accept the risk and continue" for a selsigned certificate (= generated locally using openssl, mkcert tools, etc) appears and sometimes not.

When the button is not displayed, then we got as error "SEC_ERROR_UNKNOWN_ISSUER". My question is then: "When SEC_ERROR_UNKNOWN_ISSUER is returned for selsigned certificate or not ?" Is there a way to debug and got a more verbose message to troubleshoot ?

Many thanks

Charles M.

I want to connect to a server with a self signed certificate. I add it to the Certificate Manager under Servers but Firefox refuses to connect.

How do I connect to server with a self-signed certificate?
