hello katpollock, apparently firefox is reporting a wrong user agent to websites & identifies itself as firefox 3.6.8 - please reset the user agent string as it is described in the following support article: [[Websites say that Firefox is outdated or incompatible even though it's the latest version]] please also uninstall any toolbars you don't need since they can cause additional problems: [[Remove a toolbar that has taken over your Firefox search or home page]]
