thunderbird-addon

I am thinking about writing a plugin for email application. It can be put on Gmail Labs. It can be thunderbird plugin or even chrome/firefox plugin. But to get the most exposure I should put it on Gmail Labs if possible. Actually, I don't know if it's possible at all. BTW, I'm aware of this . Let me know what you think.

I am working on writing an add-on for Thunderbird and would like to be able to cancel the sending of an email under certain conditions. I have the following code which allows me to execute code before the email is sent, but I don't know how to stop it. document.getElementById("msgcomposeWindow").addEventListener( "compose-send-message", function(){ var msgcomposeWindow = document.getElementById( "msgcomposeWindow" ); var msg_type = msgcomposeWindow.getAttribute( "msgtype" ); // do not continue unless this is an actual send event if( !(msg_type == nsIMsgCompDeliverMode.Now || msg_type ==
