Let me be the last one on the Mozilla Firebird bandwagon. In Windows, it's an improvement over Internet Explorer because it has built in pop-up window blocking and tabbed browsing which I've come to use all the time. Also, Mozilla has its own Google Toolbar called Googlebar. On a Mac, you can use Safari which also has built in pop-up blocking, tabbed browsing, and a Google search box. But I prefer Firebird because, at the moment, Safari isn't a supported browser for posting to Blogger over the web.
