In 2021, the desktop version of the Firefox browser introduced the Total Cookie Protection (TCP) feature; Some time later, it was enabled by default in the Windows, Mac, and Linux versions. Now the developer has decided to offer users the same level of privacy Android.
The TCP feature restricts some websites’ access to cookies owned by others, making it more difficult for resources that track user activity on the Internet, thereby increasing privacy when browsing. TCP is now available in the base version of Firefox for Android, having previously been present in desktop versions of the browser and Firefox Focus.
Operation of the feature involves differentiating access to cookies between websites. For example, if a user searches for shoes in an online shop, they may later see ads with the same shoe models on Facebook.* – in the absence of protection mechanisms, this is done through the analysis of cookies. If access to it is restricted, such a scenario is impossible – each website can only process the files that it itself stores on the user’s computer. The Microsoft Edge and Apple Safari browsers also offer similar data protection measures.
