Comment(by mikeperry):
Nearly every github project URL caused me to get a canvas prompt. Or at
least it did until today. Perhaps they changed their site? I wonder if we
had anything to do with that.
I will keep an eye out for other websites.
I've also noticed that PDF.js uses the canvas for image-heavy PDFs (for
example, scroll midway through http://freehaven.net/~arma/slides-
dimacs13.pdf in a TBB that has PDF.js installed, such as a Gitian build).
It would be nice to find some way to allow PDF.js to use the canvas
without allowing the website hosting the PDF to do so..
