如何产生错误？

I have a jquery/ajax website at tarh33ls.com For some reason, in firefox, i get the following error:

uncaught exception: [Exception... "Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIDOMLocation.href]" nsresult: "0x80004005 (NS_ERROR_FAILURE)" location: "JS frame :: http://tarh33ls.com/ :: :: line 26" data: no]

Line 0

but line 26 is:

if (location.href.indexOf("#")==-1) {location.href="http://tarh33ls.com/#";}

How would that generate an error?

I'm not sure why the error happens, but it seems this fixes it:

Move the if (location.href.indexOf("#") == -1 code inside the $(document).ready block (at the top of it), like this:

$(document).ready(function() {
    if (location.href.indexOf("#") == -1) {
        location.href="http://tarh33ls.com/#";
    }
    $.ajaxSetup({
...etc
