Thank you! That's something that I clearly should have thought of, I found
the error very quickly using your debug technique and is now a bit ashamed
:(

The error is at
https://github.com/re222dv/1DV449_re222dv/blob/eebacf3a78b4e9e2b947bf8cf97546f065d749a1/Laboration3/client/app/elements/laboration-three/laboration-three.html#L46
where I return an array in a databound property. Obviously I return a new
instance every time the property is called, which in Firefox seems to be
all the time.
The error is of course very easy to fix and something I should have
spotted, however as it works perfectly in Chrome I didn't... I guess Chrome
optimizes that one to only ever create a single instance of the array that
obviously never changes.

In Angular one receives a warning when a databound proerty never stabilizes
and Angular stops caring about that property. Maybe something similar could
be implemented in Polymer too to help development?
