I have a new PC running Windows 7 and Office 2010. My default browser is Firefox. I also have a website that was produced entirely in-house and is hosted by one.com (genesiswatchmaking.co.uk).
On the site there are a few .AVI videos. For some reason Firefox will not play the videos and always says a plugin is needed - but all the video plugins are up to date. Interestingly if I open the website in Internet Explorer 8 the video plays fine. Can anyone help with an explanation?
