I read recently that starting with FF 58 canvas hashing would be blocked. (https://www.helpnetsecurity.com/2017/10/30/firefox-browser-fingerprinting/) Today I updated to FF 59 and ran the browser fingerprinting tool from panopticlick.org which is part of the Electronic Frontier Foundation. (https://panopticlick.eff.org/). The results of the test show that canvas hashing was succesful and displays the hash. I tried to post a screen shot of the results but was unable to do so.

That article was based on a development version of Firefox 58.

As far as I know, this feature remains under the umbrella of the privacy.resistFingerprinting preference and is not a separate preference available without invoking that mode (which does many things).
