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.
And when you do this, you are now more fingerprintable than you were with
resistFingerprintingoff, as the specific combination of anti-fingerprinting measures and canvas-enablement makes you more unique. Which is why it's hidden inabout:config.Yeah, as stated, only for sites you trust.
I was enabling it on at a cycling site that uses HTML5 Canvas to make their charts of how long chain lubricants last zoomable, haha.
If you're fingerprintable and your fingerprint changes every 60 seconds then it doesn't really matter
You're still better off hardening these settings
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.
HTML5 is a perfectly valid technology when used for good purposes though? Their zoomable charts are fine as long as it is enabled. I don’t think they’re using them for tracking, just to make it easier to enable certain technologies.
The company I work for does all our interactive lessons in HTML5 Canvas via Animate CC. When Flash was EOL’d it saved us from having to redo literally thousands of lessons completely.
