How to handle delete message on Thunderbird

Question

I have a Thunderbird add-on and should to fix some bugs.

I need to handle deleting messages and do some actions, but I don't get any information about onDeleteEvent.

I only found this page and tried to use

document.addEventListener("onMessagesRemoved", function() {
  Application.console.log('deleted');
});  

But nothing happens.

How I can handle delete messages event?

The notification is fired on listeners of nsIMsgFolders. So you need folder.addEventListener, not document.addEventListener. You have to provide a listener for each specific folder that you want to watch deletion for.
