For example attribute EventHandler onmozbrowsererror attribute EventHandler onmozbrewsertitlechange

Hi smaug, how do you think about this? I thought it would be nice to have all the public interface of mozbrowser in one place (BrowserElement.webidl). mozbrowser currently doesn't support DOM0 style event handlers. If I'm going to fix this, what are needed other than add attributes to webidl? Do I need to touch EventNameList.h? Perhaps also nsGkAtomList.h.

(onfoos aren't really DOM0, they are just EventHandlers. addEventListener adds EventListeners ;) ) So yes, you probably need to add stuff to nsGkAtomList, and thouch EventNameList too... But I don't know currently the setup for BrowserElement.webidl, since I didn't review bug 1044736. Do we want to support also onfoo DOM attributes? <iframe mozbrowser onmozbrowsererror=""> ? If so, perhaps we want to support those onfoo webidl attributes and DOM attributes in all the elements in case <iframe mozbrowser> is enabled. And in that case just changing EventNameList.h, http://mxr.mozilla.org/mozilla-central/source/dom/webidl/EventHandler.webidl?rev=c112fdf29ed1#28 and nsGkAtomsList.h should be enough.
