As of January [1], it looks like Firefox enabled fingerprinting protection by default. Expert users may have overridden settings in various ways that could prevent those protections from being active. To verify, at Preferences > Privacy > Tracking Protection (about:preferences#privacy), make sure you've selected an option that includes Fingerprinting protection.

- draebek 6y agoNote that I think this blocking is done not by detecting a site doing it, but instead by using block lists: Firefox has a list of sites where third-party resources, including JS that would do canvas fingerprinting, will be blocked. As I understand it, this is different from the various "resistFingerprinting" ("RFP") settings in about:config, which will work on every site (and are notorious for breaking things). Ditto CanvasBlocker, which AFAIK runs on every site. I got this info from one of the links in the informative post you cited: https://blog.mozilla.org/security/2020/01/07/firefox-72-fingerprinting/ https://blog.mozilla.org/security/2020/01/07/firefox-72-fing...
- floatingatoll 6y agoYeah, I definitely wouldn’t enable resistFingerprinting for anyone I’m responsible for providing tech support to! If y’all want to experiment with it, go ahead, but be prepared to be angry at your browser and/or websites as things mysteriously break without explanation.
