Protections Against Fingerprinting and Cryptocurrency Mining Available in Firefox Nightly and Beta-Future Releases
With the advent of virtual currency, sites have emerged that try to replace advertising with revenue by mining virtual currency using the site viewer's CPU power . It is not good for users to use their own terminal for mining because it drains the battery.
In conjunction with Startup Disconnect , a developer of anti-tracking tools, Mozilla has compiled a list of domains that provide scripts for mining, and announced that the beta version of Firefox has added an option to block access to those scripts.
This option was implemented in 'Firefox Nightly 68' and 'Firefox Beta 67', both of which are disabled by default, but can be enabled in the 'Content Blocking' section of the configuration. Testing with a small number of users for several months is likely to be a while ahead of the stable Firefox implementation for general users.
In addition, the block function of technology ' fingerprint ' that can be identified and tracked as the same person even if you are using different browsers is also implemented at the same time.
