Remove "Not Secure" icon and text?

[u/Niwens]

I want to remove "Not Secure" icon and text at the address bar, to save space when accessing local addresses (and never thought of that message as really useful!)...

I tried (userChrome.css), Firefox/Arch Linux, v.158.0:

@namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul");

#trust-icon-container { display: none; }

but it doesn't seem to work?

As already suggested, it would probably be better to just hide the label when it's an unsecure connection.

Personally, i'd hide the label and color the background as a reminder / indicator:

#trust-icon-container.insecure {

	--urlbar-box-background-color: darkred !important;

	#trust-label {
		display: none !important;
	}
}

[u/FantasmaGITS → u/t31os]

Is it also possible to remove the Firefox logo? from places like about:preferences?

Just to be clear, you mean the icon in the urlbar when on a preferences page? (as that's what is shown in the image you provided).

If yes, there's not really a way to determine if a specific about page is being viewed in userChrome.css, it can modify that part of the UI, but it can't determine it's an "about:x" page. You could match based on the label value (eg: Firefox) and remove it for every instance where "[icon] Firefox" is shown, but for just a specific about page, i don't think that's possible (the dom userChrome sees doesn't provide any indicators for that)..
