"I am very thankful for the gecko preview. I have been programming(?) HTML and CSS for 9 years, and had no probs when 98% of my hits to my site came from IE, but now, 29% come from Firefox, and many shortcuts and spans/divs do not show the same without exact code. That preview has been invaluable and saved a lot of time, and I believe may have contributed to an increase in visits.
I would like to see it as all one download, or as a standard feature as firefox is taking so big a piece of the market now."

"What am I supposed to do when the error message "Class not registered" comes?"
