Re: New website - back to the old unicorn!

Hi Stefan,

This seems very suspicious for one reason. I cannot see "Canvas"
anywhere in the entire codebase of the website, or any loaded 
resources.
So I have no idea where on earth the JS you're finding has come 
from -
I'm guessing it's improperly injected by a extension. FWIW I also 
run
Decentraleyes in Firefox and fail to see your issue.
