We discuss the benefits of combining user studies and cognitive modeling in the context of Firefox tabbed browsing. We studied new users' ability to use tabbed browsing without assistance, and then evaluated alternatives for closing browser tabs to improve the new user experience through user tests and cognitive modeling. In general, our experience highlights the advantages of using user studies and modeling together to do user interface evaluation: user studies provided validation of design intuitions and data to support modeling of user behavior; modeling provided a fast and efficient ability to play "what if" with the design change; the combination of qualitative user test data and quantitative modeling results proved to be a far more convincing package of evidence than either result in isolation, given the variety of perspectives inthe design and development team.
