Hello,  Users whan to change Quote in replay message.  Previously there was a changeQuote plugin for this, but now it doesn't work (TB 102)  For example, deffault header is:      And user need change it.  The user can change the setting mailnews.reply_header_type, but this is not enough.  For example, i user whant this headers:      I already have such a plugin, I made it myself, but it uses experiment_apis, for this reason I am not ready to share it.  When open messengercompose, i register event:        window.addEventListener("compose-editor-ready", new my_windowListener(), {once: true});        in my_windowListener, i create new headers, and push it in "moz-cite-prefix", example:        				let STR = `
				 <hr size=1 width=100%>
				<b>Subject:</b> ${Subject}
				<b>From:</b> ${From}
				<b>Sent:</b> ${Sent}
				`
				let div = doc.getElementsByClassName("moz-cite-prefix")[0];
				div ? div.innerHTML = STR + "</br>" : null;        user can change headers in GUI settings, how he need
