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. -- Timothy Stefan Nobis writes: > Hi. > > Thanks for your great work and the wonderful new page! > > A minor detail: I use the plugin "Decentraleyes" and with this > activated there is quite a bit JavaScript garbage at the end of > the > page (below the "Created by" footer).
