Did you know that Firefox is smarter than IE? Maybe it just makes more assumptions and those assumptions are usually right. If you want to go to a fairly common site, enter just the name of that site like “digg” or “cnn” and hit enter. FireFox will go to digg.com and cnn.com respectively. Does it just add “.com” to the word you enter? Probably not because “ford” takes me to ford.com while both “ford trucks” and ford cars” takes me to fordvehicles.com. “Internal” takes me to irs.gov, while “iteral” takes me to a Google search for the word. Looks like you are better off sticking to most common sites but this can save a few keystrokes.
