Comment (by cypherpunks):

 Workaround above changes behavior for non-gtk platform which can to handle
 ''transferable'' with null data flavor and to clear clipboard. It's
 possible to modify proposed patch and to change behavior on gtk platform
 instead, like this:
 {{{
       if (nsIClipboard.hasDataMatchingFlavors(["application/x-moz-private-
 browsing"],
                                               1,
 nsIClipboard.kGlobalClipboard)) {
           var xferable =
 Components.classes["@mozilla.org/widget/transferable;1"]
 .createInstance(Components.interfaces.nsITransferable);
           xferable.addDataFlavor("");
           nsIClipboard.setData(xferable, null,
 nsIClipboard.kGlobalClipboard);
       }
 }}}
 It should to clear clipboard and to keep the same behavior for all
 platforms. Need testing.
 Another solution to modify browser code
 (nsClipboardPrivacyHandler::Observe) to pass not null flavor?
