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.

And when you do this, you are now more fingerprintable than you were with resistFingerprinting off, as the specific combination of anti-fingerprinting measures and canvas-enablement makes you more unique. Which is why it's hidden in about: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

Why would you assume your fingerprint would change every 60 seconds? Are you flipping all the settings every minute or so?

[–] delirious_owl@discuss.online 3 points 8 months ago (1 children)

I use the plugin Chameleon to chagney my browser attributes every 60 seconds so my fingerprint changes constantly.

Will I agree and are also a Chameleon user... There are so many attributes that makes you finger printable that I'm slowly thinking to switch to Tor.

In that case remember not to use any plugins, don't change any of the default settings, and run with a 1080p resolution, never maximize the TOR window either. Since even screen size and resolution is used for your fingerprint.
