So I uploaded a page I created a few years ago to use as my 404 error page, I get the following in my error consol in firefox, but everything seems to work ok. I need to know if the page loads ok in Internet Explorer. You can just pick any random url it is a 404 not found page, I have been using: http://automation-repair.com/ibgfk.html What do you think? Does it work in IE? Do I need to update the javascript? Warning: Use of captureEvents() is deprecated. To upgrade your code, use the DOM 2 addEventListener() method.
