All I can say Firefox is faster than Internet Explorer at the moment. Just takes a bit of getting used to.And a few programs have to be added. No idea about Google Chrome but I am sure someone will give you advice on that one. I have been quite happy using IE8 but just recently it has slowed down a bit so decided to try Firefox. I am using I/E8 at the moment as I was having trouble connecting to this site with both browsers. It looks like quite a few others are having the same problem.
I know this is a stupid question, but I just clicked a link to download Firefox, and in the box it asks if you want to save or run the file. Which one do I tick please? (I`ve never been sure about that!!!)
