Presumably. See http://hg.mozilla.org/integration/mozilla-inbound/rev/57714b421d53.
I think we'll need to replace the line
var line = script.getOffsetLine(state.offsets[i]);
in content/firebug/console/errorStackTraceObserver.js by
var line = script.getOffsetLocation(state.offsets[i]).lineNumber;
for recent Firefox versions.
@simonlindholm How can I reproduce the issue?
I don't know, I just saw the commit. Something involving uncaught (or also caught?) exceptions, the Script panel, and the option to show stack traces for errors in the console, probably.
