If you haven't switched to Firefox yet, you should -- it's very powerful and will save you a lot of time in the long run.  Here's one example:  Instead of typing www.google.com in the browser, you just type google and then hit ctrl-enter instead of the regulare enter key.  Ctrl-Enter adds the "www." and the ".com" pieces of the url automatically.  That's 8 characters that you don't have to type -- over the course of a month this adds up to hundreds or even thousands of saved keystrokes. 

Firefox also has some excellent add-ins for you to use -- some of the most useful for online business owners are the web design toolbar, css editor, ftp plugin, and html code validator.  There are hundreds to choose from, and you'll find a new one every week that will save you time, and in the long term, money.
