See also bug 923746, OS X plugins are semi-windowless, but use some native widgets similar to windowed-mode plugins

John, is this a dupe of bug 923746?

(In reply to Brad Lassey [:blassey] (use needinfo?) from comment #2) > John, is this a dupe of bug 923746? Most likely. IIRC OS X always uses some manner of native widget code even in "windowless" mode, so flash is not expected to work without windowed support.
