from a ff 3.6 plugin I want to get notified every time a new window object is created before any JS on the page has run – I tried the “load” event but it seems to be too late, some JavaScript has already been executed by the time I get a handle on the object and I need to be in before any JS is run, does anyone have any ideas please?
You need to listen for the
content-document-global-creatednotification, that’s exactly what you are asking for – a window has been set up but no JavaScript code had a chance to execute yet. This is supported starting with Firefox 3.6.6.You need to use nsIObserverService and register your observer for this topic. When your observer is called the subject will be the newly created window.
