Mozilla is adding a new feature to protect you against web annoyances in future releases of Firefox. The new feature is currently available in the beta version of Firefox 67, and the nightly version of Firefox 68. They will be available in the stable release of Firefox in a few weeks.
The cryptomining and fingerprinting blocks work pretty much like anti-tracking blocks in the current version of Firefox. The company has partnered with Disconnect to include scripts that prevent your browser from loading disingenuous content.
