My first project this summer as an intern at Mozilla on the Firefox team was to improve the form history feature. It's a feature that most people use when they fill out forms but don't even realize it. For those of you who don't know what I'm talking about, it's the dropdown of previously submitted text that appears when typing into a form input field. The two main improvements that I have been working on in form history (which are also known as form awesomecomplete) for Firefox 3.6 are detailed below.
