I get the below error on Firefox at the bottom of the component, though everything works fine.

TypeError: fn is undefined throws at https://impact-dev-ed--ilms.na16.visual.force.com/auraFW/javascript/XyhLNaMJXc3t5qwu_xzuTA/aura_proddebug.js:14073:9

I'm not sure where/what to look, could you please give me some pointers/suggestions.
