Protections Against Fingerprinting and Crypto Mining in Firefox Nightly and Beta
We have added a feature to block fingerprinting and cryptomining in Firefox Nightly as an option for users to turn on. Now in the latest Firefox Nightly and Beta versions, we give users the option to block both kinds of scripts as part of our Content Blocking suite of protections. In the coming months, we will start testing these protections with small groups of users and will continue to work with Disconnect to improve and expand the set of domains blocked by Firefox.
