Well as far as I can assess it, your site appears to be working OK. So this problem you are having with the title line of that page must be something that is only visible by you. So with that in mind, it could be something simple such as browser cache, so clearing your browser cache might help?

You will find links in that page for all the other major browsers support sites.
