UPGRADE YOUR BROWSERS. If ONLY for security reasons. IE 6 is 7+ years old, and IE 8 is currently available in beta.
Allow me to help:
Firefox: Fast, safe, updated all the time. Most popular alternative to IE.
Safari: My browser of choice. Also very fast, safe and a wonderful Apple experience.
If you must, download IE 7 or use your Windows Update (found in the start menu).
Have a favorite IE 6 alternative? Post up in the comments.
