I suspect you're using Microsofts Internet Explorer, at the moment. I used IE for around 3 years until a couple of weeks ago when I downloaded Mozilla.
I find this browser to have as much support as IE does. IE is more prone to spyware etc, that you get on in-browser search bars and all that other nonsense. It's more stable, more user friendly and the makers offer far more support than Microsoft do for IE. I would definately recommend Mozilla. The only drawback I find, is that Mozilla takes more time to load than IE does, this is because it isn't wrapped up with Windows as much. Which, I suppose is a good thing. Good luck with your choice :)
