I’ve been using FireFox for a while now. Recently there’s been a lot of crap about IE and another exploit of the day (FireFox isn’t without it’s problems too). With every new version it just gets better, as well the constant availability and improvement of all sorts of extensions to it, as well as a growing number of themes to make it look even better.

They also have a built in Google Toolbar. It even supports features not available in the Google-provided IE toolbar! It has an amazing extensible search functionality:
