Hyperlinks Formatting

I used this css to format my hyperlinks:

I applied the css using "External HTML Object" at the Title level. see this image: http://screencast.com/t/ZWQ0YTgzYjYt
The Hover property works great in firefox and IE. See this video: http://screencast.com/t/MDJkYmVjMGE
The Visited property is only working in IE. See this video: http://screencast.com/t/NWQzY2Nj

What am I missing here?

Thanks,
