Iframe contains a javascript function (only an alert), which i call with the "Test JS!" button. I press "Insert iframe!" more times, "Test JS!" working. But after this, if I press one more the "Insert iframe!", the "Test JS!" is not working anymore. "Test JS!" (after a "Insert iframe!") is working more times, but AFTER one alert function the following "Insert iframe!" still works, but the "Test JS!" is not. It's only a FireFox issue, IE7 and Opera not affected. Reproducible: Always Steps to Reproduce: 1. Press "Insert iframe!" 2. Press "Test JS!", alert appears 3. Press "Insert iframe!" again 4. Press "Test JS!" again, alert not working anymore

Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.2a1pre) Gecko/20090122 Minefield/3.2a1pre This fails indeed but works in latest Opera. This is not a (recent) regression.

May be related to bug 473436.

Not at all. It's related to the fact that window.iframename keeps pointing to the old frame. Almost certainly a dup of bug 170799 (and _definitely_ in the wrong component).

I cannot reproduce the problem in Firefox22.0 and later.
