When new users visit applesliced.com, a jquery popup appears to request the users zip code. Prior to Firefox 4 (and in all other browsers I have tested), this popup loads quickly and flawlessly. In Firefox, the "Save" image (input type="image") frequently hangs and the Input text field (input type="text") hangs for several seconds before the user-entered text can be seen. I have tried three different jquery plug-ins to display this popup. Input text fields elsewhere on the site work correctly, but for whatever reason when an HTML "input" is loaded there is a delay in rendering. Once a user enters their zip code, you can recreate this problem by clicking "My Zip Code (edit)" on the right side of the navigation menu.
