Usign gBrowser and observerService to find a tab on startup?

Instead of filtering first and then adding the load listener, you could use gBrowser. AddEventListener("DOMContentLoaded", myfunction, false) to listen for page loads on all tab documents and then only run your code based on the url.

The "sessionstore-windows-restored" notification is sent when the tabs from the previous session have been restored and the loading in these tabs has been started (sometimes: "Don't load tabs until selected" option means that the load isn't even started in the background tabs). But the location of these tabs is still about:blank until the server is contacted because the address loaded might redirect or the server might be unreachable (meaning an internal redirect to about:neterror). Firefox only changes browser location when content is definitely being served from the new location.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
