I've got the same problem when i have the form of fields and "done editing" submit button, because when Selenium IDE auto-click the javascript function, that responsible to disable confirmation window (leave page or still on it), it does not take "mouseup" mouse event that mean window.confirm still works and auto-pass test was fails. My solution is override javascript function window.onbeforeunload in this case (no need to ask if we know that we do when we record test in Selenium IDE). You can run override script in the Selnium IDE before click on "Save" (or something like this) button through selenium.runScript - it should simple disable the confirmation window.

    Command: runScript
    Target: {window.onbeforeunload=function(e){};}
