One other point. You say that FF inserts code automatically if the editor is empty and CE cleans it up, which triggers the change event.

 

In our case, the editor is not empty, since we populate it with a default setting. Therefore, there's no reason for the change event to be triggered...

 

Another point: if we try to call getHTML via Firefox, FF throws this error:

 

Error: [Exception... "'Permission denied to get property HTMLDocument.body' when calling method: [nsIDOMEventListener::handleEvent]"  nsresult: "0x8057001e (NS_ERROR_XPC_JS_THREW_STRING)"  location: "<unknown>"  data: no]

 

So we really need a solution that simply ignores the mouse click...
