So github uses \"defunkt\'s\" PJAX module (https://github.com/defunkt/jquery-pjax#events), and I\'m making a firefox addon that needs to listen to the event pjax:end
As far as I'm aware its not currently possible to catch jQuery events using native JavaScript (although looking at this bug ticket http://bugs.jquery.com/ticket/11047 it appears that there are some library's that would enable this, but not without code changes to the PJAX code).
