I am trying to implement an auto save feature where user input text and drop down selections will be saved in session so that user can leave the page and come back again for more editing. I am doing an Ajax call ($.post) to save after every three seconds. Its working fine with IE 7/8 but not in firefox. It makes the Ajax call and stores it in session but once I leave the page and try to come back, no javascript methods can be found. This is what firebug reports when trying to call a "start()" function on window load event - "startis not defined". Since I repopulate the textbox on window onload event, my textbox is empty on return. Also all the dropdown selection onchange event handler functions are not working anymore. I am using jquery 1.3.2, Firefox 3.5.5, JSP and servlet. Any ideas?
