Site only tracks Firefox after 0.9 update

I have a mystery on my hands, after updating to 0.9 I notice one site(aspx page) that I am tracking is only registering Firefox hits. I tried to open the page with all other browsers but only when I use Firefox would a hit show up in Piwiki.

I created a new tracking tag and replace the old one and it had no effect, also I took the old tag and placed it into an empty HTML page and it started tracking normally again. I am tracking several other site with no issues at all and this site was tracking fine before the update, any thoughts or advice?
