Would you be able to take the "debugger" calls out of the production code?
edit: After some more testing, in Chrome I can make it work by just closing the Dev Tools windows, but Firebug gets caught up on it as long as it is enabled, even if not open currently. This means I have to disable Firebug entirely in order to use this on my page. I don't really want to do that, as I am using it in my workflow for otherwise debugging the code I manage.
