New method of Internet tracking spreads: Canvas-Fingerprinting
The tracking technology "Canvas-Fingerprinting" makes Internet users glass human. Researchers say one can hardly protecting against it. The new tracking technique can hardly be noticed by the average user. Only switching off the Java script function in browser would help, but then many pages not work properly.
Especially the company of AddThis is responsible for the dissemination of the disputed technology, which Facebook and Twitter buttons will provide on 13 million Web pages. They hid the canvas-fingerprinting technique at least on a part of the Internet pages between the popular buttons...

There is a Firefox plugin called Privacy Badger that is supposed to block this.Originally Posted by jwoegerbauer
I don't know about Evercookies though. They will keep popping up like a virus.
Update: A deletion of features that work well and ain't broke but are deemed outdated in order to add things that are up to date and broken.
Compatibility: A word soon to be deleted from our dictionaries as it is outdated.
Humans: Entities that are not only outdated but broken... AI-self-learning-update-error...terminate...terminate...
Tools that block tracking cookies won't work for Canvas-fingerprinting. Canvas-fingerprinting uses the HTML5 canvas element. If your browser displays HTML5, it is going to work regardless of the extensions and blockers you have installed. That's the point.
As one can read at EFF's site:
So Privacy Badger - an extension for Chrome and Firefox - currently isn't helpful at all.Does Privacy Badger prevent fingerprinting?
Currently, Privacy Badger does not prevent browser fingerprinting, of the sort we demonstrated with the Panopticlick project. But we will be adding fingerprinting countermeasures in a future update!

How about "NoScript" (Firefox add-on)? Yes it blocks JavaScript but the base page still loads and then it lets you choose what scripts to run. Yes it can be a pain but I guess it all depends on how you value your browsing experience Vs privacy. Its interesting to run just to see what trys to load.
If a man says something in a forest and there is no woman there to hear it, will that which has been said still be wrong?
Some people are like clouds. When they go away its a beautiful day.
FYI:
Which web-sites currently are using Canvas-Fingerprinting, are listed here:
At time of this writing 5,619 sites!
So you could check sites against that list, but it may not be updated frequently enough to catch new offenders.
HINT:
: I've done so.

I believe that rather than adding 5,619 URLs from that list to your HOSTS file, you can just add the Fingerprinting Domain URLs (there are only 23 unique Domain URLs) as follows (I've already added the 0.0.0.0 for you):HINT:
: I've done so.
I think that should stop the other five thousand-odd URLs from being able to contact the third parties above, thereby disabling fingerprinting, but please correct me if I have it wrong?Code:0.0.0.0 49winners.com 0.0.0.0 addthis.com 0.0.0.0 amazonaws.com 0.0.0.0 chatrooms.org.in 0.0.0.0 cloudflare.com 0.0.0.0 cloudfront.net 0.0.0.0 cya2.net 0.0.0.0 domainsigma.com 0.0.0.0 freecall.com 0.0.0.0 freevoipdeal.com 0.0.0.0 hediyera.com 0.0.0.0 insnw.net 0.0.0.0 kitcode.net 0.0.0.0 ligatus.com 0.0.0.0 meinkauf.at 0.0.0.0 nonoh.net 0.0.0.0 pof.com 0.0.0.0 rackcdn.com 0.0.0.0 revtrax.com 0.0.0.0 ringier.cz 0.0.0.0 shorte.st 0.0.0.0 vcmedia.vn 0.0.0.0 voipbuster.com

Not sure whether your proposal will do the job. Will test it, ASAP.
UPDATE:
1. Started FF, loaded youporn.com (IP: 31.192.116.24)
2. Privacy Badger : No trackers found
3. Investigated page's content: No occurrence of term AddThis (neither in upper nor in lower case)
4. Closed FF
Nevertheless, I'll keep you updated.
UPDATE 2:
1. Started WireShark
2 Started FF, loaded youporn.com (IP: 31.192.116.24)
3. Closed FF
4. Closed WireShark
5. Walked WireShark's TCP/IP packets protocolled: AddThis.com (IP: 208.49.103.220) wasn't to find in
UPDATE 3:
As in between I have read, YouPorn, according to their own, after becoming aware of the Canvas-Fingerprinting test, threw AddThis from their site.
So I've wasted my time.
