Hello, For the past few weeks, tjr and I have been working on a patch for Firefox RFP which will fuzz the canvas, the feature is now in Firefox Nightly and seems stable. The rationale for this change is already expressed very well by tjr in the description of <https://bugzilla.mozilla.org/show_bug.cgi?id=1621433> and I am not going to try to butcher it. With that, I invite you to test out this feature in Firefox Nightly. Best, Sanketh
