Firefox has always concern itself with users privacy and base on this reason, it has brought one of its best features to the Android version of the Focus browser. The feature is called Total Cookie Protection and it prevents cross-site tracking.
Firefox is doing so by storing the cookies into a virtual “cookie jar” and prevents websites from accessing information about your online behavior. This is standard practice for ad targeting so that the companies know what your shopping preferences are.
The Total Cookie Protection has been part of the desktop version of the web browser and is enabled by default, but porting it to the Android version took some time. In fact, this is the first mobile browser to offer such feature.
Since some websites won’t work properly with the browser blocking access to the cookies, it uses SmartBlock and other related features to keep said websites operational.
