FWIW I got some of the way through embedding a PDF viewer in Tridactyl [1] so that the keys would still work there, but I backed off because I was a bit scared by how frequently pdf.js gets updated. In Tridactyl it'd get updated about twice a year so we might end up with unresolved security issues.
Maybe there's a solution I've not thought of (CDN?).
