People who really feel the yen to mess with this can GetInterface an nsIURIContentListener and set the attribute there (which is equivalent). Note that embedders use the frozen nsIWebBrowser.parentURIContentListener, so this doesn't even affect them; it only affects our internal non-nsWebBrowser-using code.

Comment on attachment 175096 [details] [diff] [review] Proposed patch + // XXXbz this is never unset! Someone needs to read the idl. please update nsIURIContentListener.idl to actually mention this... xpfe/browser/resources/content/nsBrowserContentListener.js (et al) I also believe the usual style is the dot on the new line...

The composer code is actually ok, since it implements nsISupportsWeakReference (I removed the XXX comment). Filed bug 283197, bug 283198, bug 283199 on the JS files.
First patch checked in.

Comment on attachment 175180 [details] [diff] [review] Updated interface comments + * nsnull value hm... since interface comments are generally js-focussed (@return/@throw etc), I'd just say "null" here. (twice)
