Description
The Content Blocking/Tracking Protection feature stops Firefox from loading content from malicious sites. The content might be a script or an image, for example. If a site is on one of the tracker lists that Firefox is set to use, the fingerprinting script (or other tracking script/image) will not be loaded from that site.
Cryptomining scripts use a computer's central processing unit to invisibly mine cryptocurrency.
