Anti Fingerprinting

Unread postby pm4eva » Wed, 12 Sep 2018, 16:42

I know PM does fake some canvas things but it seems its not enough.

If you look the Canvas Blocker Addon
https://addons.mozilla.org/de/firefox/a ... asblocker/
for Firefox you will see the difference.

It fakes (blocks) alot more.

There is also a testsite for the AudioApi made by the developer of Canvas Blocker.
https://kkapsner.github.io/CanvasBlocke ... oTest.html
(Maybe the site needs pressing F5 to refresh )

So the question is if you could include that functions in PM directly,
or is an Addon existing what we could use in PM instead?

From what I understand, the difference between Pale Moon's built-in functionality and add-ons like this is that Pale Moon does not block access to the APIs (which means less things on the web will break) and instead implements canvas "poisoning". This means that canvasing will return slightly randomized data every time it's used, effectively randomizing the fingerprint instead of preventing it. However, this "poisoning" feature only applies to canvas fingerprinting, not other forms of fingerprinting such as what that add-on lists.
Linux Mint 18.3 Cinnamon (64-bit)
Windows 7 (64-bit) (Sometimes)
Windows 10 build 1803 (64-bit) (Sometimes)
We are our choices.

If you use the Link for testing AudioAPI (ID fake) with PM and FF (with canvasblocker addon) then you will see that in FF the ID is always different and in PM always is same.
So the Addon also fakes that too.

I dont know what could be implemented in PM,
and i dont know what other things would be good to have also.

Thats why i ask.
What make sense and what not, and what could be implemented?
In FF i fake all (not block) with that addon.

p.s. there is another Addon what only fake the AudioApi
