Description

https://developer.mozilla.org/en-US/docs/Web/API/CanvasRenderingContext2D/filter got added in Firefox 35. We should investigate its fingerprinting potential. This can at least wait until we prepare an ESR 45 based release as this feature is still behind a preference in ESR 38 (canvas.filters.enabled is set to false)

Using a canvas is not allowed by default, thus this is not such a high prio but it would be good if we could look at it during the esr52 transition.
