to defeat canvas size fingerprinting in firefox:

about:config -> set privacy.resistFingerprinting to true

about:config -> create new boolean key privacy.resistFingerprinting.letterboxing set to true

this will set your canvas to a common size which fits in the viewport and display a grey "letterbox" border in the surrounding space.

Doesn't seem to work... reported canvas size is still some odd value (2200x1283x24). I think it uses a fixed size for the letterbox, which is useless. Right general idea though.
