Firefox is quickly becoming the browser of choice for most people. It has enhanced security features, which makes your browsing less vulnerable to viruses and malicious code. It is also quite customizable, with hundreds of addons and plugins available for free.
You can download Firefox here.
To use the Studio applets, you will also need to install the Java Runtime extension for Firefox, which you can find here .
One of the handiest addons that I've used is ColorZilla, which allows you to select any color on a web page and copy it for use in another program. For instance, you might like a particular color in one of the drawings in the studio and want to use it in one of your own drawings.
ColorZilla can be found here.
