ProTip: If you enabled resistFingerprinting, you have to manually allow HTML5 canvas usage per website (mastodon.social)

My apologies to the Bugzilla team for wasting their time holding my hand on this one. Would have honestly never noticed the little "HTML5" info icon to the left of the URL bar though without their help.

Yeah if it even drew something like “Canvas approval needed to see this image” or just the dang icon in the location bar that would be a start.

I suspect the assumption is that if you are okay digging into about:config to turn on the feature, you're okay with all further interactions veins similarly hidden.

Yeah, I guess to a degree? This all came about because I went to fingerprint.com and realized they could track across VPN etc. was trying to figure out how to block it and that came up. And since not many sites use HTML5 canvas, I had long forgotten I enabled it by the time I hit a corrupted looking graphics site.

I think in the end it shows they really need a better way to inform you what is going in than striped lines instead of a canvas graphic. Something that prompts you to either allow HTML5 canvas or that at least has a message/image you can google for further info in the issue easily.
