I was reordering my Umph, when the storefront asked me to enter the credit card number...
Let's see... Four zero one eight... WTF?
Found out Firefox had remembered my credit card number from the last time, because it offered the number for auto-completion. -_-;
Means... I'll have to nuke the auto-completion database because I've ordered so many things from different online stores on this computer, and I don't want my CC number stored anywhere on the disk. OTZL</span>
