Firefox
Because of all the recommendations to stop using Internet Explorer, I decided to give Firefox a go. There were no problems getting it downloaded and working. The download was 4.7MB and allowed the existing IE settings/favourites to be automatically imported. What I particularly like about Firefox is that the rendered pages look pretty much identical to the equivalent web page rendered in IE (so all the pages designed with IE in mind look like they're "supposed to". It also includes tabbed pages for web browsing. Tabbed web pages are such a natural for web browsing, I really don't understand why all browsers don't have it as standard functionality. I'll be using Firefox as my primary browser for the next few weeks and see how things go. So far, it "just works" and is a wonderful example what open source software can be at it's best.
