Firefox Extension trigger twice with load function

[Aubrey]

I am new to Firefox extension development.

I have started to work on an extension that triggers when the page has
been loaded. The problem I have is that the event is triggered twice.
Its almost as if two threads are created when the users navigates or
browses web sites.

Why does this happen and how could this be changed to only trigger
once.

I have attached the files.

Here is the browser.xul file

<?xml version="1.0"?>

<!DOCTYPE DOMDropper SYSTEM "chrome://DOMDropper/locale/
translations.dtd">
<overlay id="sample" xmlns="http://www.mozilla.org/keymaster/
gatekeeper/there.is.only.xul">
<script src="blah.js" />
</overlay>

Here is blah.js

var Blah = function () {

return {
init : function () {
gBrowser.addEventListener("load", function () {
Blah.run();
}, false);
},

run : function () {
alert("Trigger!");
}
};
}();
window.addEventListener("load", Blah.init, false);

Did you ever find a solution? I am having the same issue. Let me know.

Thanks,

Hi Kushal,

Perhaps, if you could show an example extension, other people might be
able to help you find the cause of this problem.

Martijn
