I'm using Firefox 55.0 (64 bits) and can't get imoin to do anything useful, I've just installed it since nagios watcher doesn't work with the new firefox anymore.

If I click on the imoin icon I get a new window with lots of 'undefined'. Could it be the URL? What is the correct URL to Icinga 1.13? Is it just '/icinga' or '/cgi-bin/icinga/status.cgi'?

I've tried a couple of different formats but nothing happens.
