There is a critical Firefox update available, Firefox v1.0.3. This includes several security fixes, and a “Fix to improve update process”. Lets hope that after this release we will no longer have to re-download the entire 4.7MB installation file just to patch a few security holes.
I cannot urge how important it is that you download Firefox and set it as your default browser. This will save you from most viruses, browser exploits, spyware and advertising that you can get on the web by using Internet Explorer. It also is a lot easier to use, more extendible (you can add tons of new features and themes to it) and is updated/patched a lot faster than IE so you are always safe.
