Also while I know this is a little off topic I noticed in that screen shot there was a button on one of your tool bars saying Armorgames.What is the purpose of that button,and if its an add-on then what is the add-on's name?If this has been happening for a week then there may be a glitch within one of your add-on's that could cause something within the site to become incompatible with the browser.
It is just a link that was added to the toolbar.
And this does not seem to be an issue with how AG is running. It looks like it is just a problem with the advertisement. I think most people would rather have a mistake happen on the page like that... lol.
