Syntaxerror: Failed to execute 'appendChild': Identifier 'ffCalc' has already been declared #67
Description
Lately I've stumbled upon this error in my JS console, it occurs on pageload:
It does not seem to break anything, but would be nice to not have it ;)
It does not occur 100% of the time, mostly on first pageload. When refreshing it does not seem to occur anymore.
