Javascript Firefox problem

I am trying to execute the following code from a firefox extension but it is not working. The actual code inside the else part was different but even this simple for loop is not getting executed. alert box without the for loop is working. Can someone have any idea about why this is not working. Thanks

window.addEventListener("pageshow",function(e)
    {
        if((document.title.trim()=="Mozilla Firefox") ||
           (document.title.trim()=="New Tab"))
        {
        }
        else
        {
            for(i=0;i<3;i++)
            {
                alert("hi");
            }
        }
    },true);

If it's inside a Firefox extension, try using content.document instead of just document.

EDIT: 

var metaTags = content.document.getElementsByTagName("meta");

for(var i = 0; i < metaTags.length; i++) {
    // do something with metaTags[i]
}

Also, if it helps, feel free to look through the source of any of the extensions I've written.

document.title.trim()

Are you sure that's what you want? String->trim() is a non-standard JavaScript method so far only available in Firefox 3.1.
