So far it appears that this only happens when a popup window is opened, and only in cases where the domain in the new window is different from the one that opened the window. Since most add-on scripts rely on the load handler being called, many of them will not work in the newly opened popup window. There&#8217;s more information about this in <a href=\"https:\/\/bugzilla.mozilla.org\/show_bug.cgi?id=799348\">bug 799348<\/a>.<\/p>\n<p>At the moment we consider the impact of this bug to be fairly minor, so it won&#8217;t be fixed until Firefox 17 unless there are sufficient reasons that merit the creation of a 16.0.1 update.
