Add an option to prevent canvas fingerprint: https://addons.mozilla.org/firefox/addon/canvas-fingerprint-blocker/

lordraiden commented 8 years ago

This is the best alternative right now https://addons.mozilla.org/es/firefox/addon/no-canvas-fingerprinting/

A must read https://multiloginapp.com/how-canvas-fingerprint-blockers-make-you-easily-trackable/

Experimental - it has no Privacy Policy: https://addons.mozilla.org/en-US/firefox/addon/no-canvas-fingerprinting/reviews/815207/

I like the idea behind Canvas Defender, but when performing some code profiling, it looked like it was the cause of slowing things down a bit. Not a huge amount, mind you... but enough to be a concern.

Atavic commented 8 years ago

One concern is: this addon is experimental as it doesn't reach minimum mozilla standard by not providing any privacy policy whatsoever.

Gitoffthelawn commented 8 years ago

@Atavic I agree, that's concerning. It's a bit odd that there is no policy, given that it's written by a company, and they have a privacy policy for their website: https://multiloginapp.com/privacy-policy/

LimboSlam commented 8 years ago

Haha! There has been a much longer, living add-on which does the same thing and maybe more. It's called CanvasBlocker: https://addons.mozilla.org/en-US/firefox/addon/canvasblocker/. Now I'm pretty sure this one has a Privacy Policy, at least last time I checked.

Gitoffthelawn commented 8 years ago

@LimboSlam Very true, but read the second link in the second post in this thread for an article about downsides to using the technique employed by that extension.

CanvasBlocker vs. Canvas Defender

I see the 2nd link on this post a little biased IMHO. You can counter that with this text, partially taken from the Tor Project.

Just pointing at more ideas about this Randomization vs Obfuscation vs Uniformity strategies, as I don't look at :-1: anyone.
