 Replying to [comment:11 brade]:
 > Mark and I are looking into a way to suppress the error console message
 that we saw.

 Unfortunately, it seems that suppressing the Browser Console message that
 I mentioned in ticket:14716#comment:9 will be difficult.  Minus a few rare
 cases, whenever an exception is throw across an XPConnect boundary it is
 logged to the Browser Console.  See:
 http://mxr.mozilla.org/mozilla-
 esr31/source/js/xpconnect/src/XPCWrappedJSClass.cpp#891

 The good news is that the fix we already have on the bug14716-loginmgr-01
 branch within the brade repo appears to fix this ticket as well as #13254
 and most of the tickets that were marked as duplicates of that ticket.  So
 it is a huge improvement, as Georg predicted!

 However, I still see the symptoms described in #13926, so that must be
 caused by something else or some aspect of nsLoginManager.js that we did
 not patch.  It takes 5 or 6 cycles of opening and closing the Page Info
 window and certificate viewer to produce the problem, which makes it more
 difficult to debug.

 For TB 4.5, I think we should go ahead and merge the fix we already have,
 i.e.,
 https://gitweb.torproject.org/user/brade/tor-
 browser.git/commit/?h=bug14716-loginmgr-01&id=f0fe46bcec5946e94fd66792983b1f081913a74f
 We can pursue an improved fix as part of our ff38-esr efforts.
