Daniel and all, I am also seeing this same behavior. I'm using FF 3.0.6. I have tried various arrangements of the code using all the examples from the plugin's webpage, but it always submits via non-AJAX. Also, if I try to use an options param to ajaxForm rather than a function callback, it will oddly enough trigger the "beforeSubmit" and "success" callbacks of the options immediately upon loading the page. Here's my code (with the options param variation): http://pastie.org/393825
