Mozilla has released Firefox 65, which includes enhanced, configurable protection against online tracking.
The organization has also published an official anti tracking policy that effectively maps out the direction which its popular browser will take when it comes to blocking online tracking.
Enhanced Tracking Protection controls
Users can choose between the:
- Standard setting, which makes it so that known trackers and their cookies are blocked only in Private Browsing mode;
- Strict setting, which blocks known trackers, including third party trackers and tracking cookies, in all Firefox windows; and
- Custom setting, which allows users to choose whether trackers will be blocked only in Private Browsing mode or all Firefox windows and whether to block cookies from third-party trackers, unvisited websites, all third-party cookies, or all possible cookies.
“Blocking all-third party cookies (…) gives you more privacy protection, but it may cause websites to break and also cause you to see just how pervasive tracking is,” Mozilla warned.
“Blocking all cookies (…) will ensure that you’re not being tracked, but it will definitely break parts of the web.”
Mozilla’s anti tracking policy
Mozilla is vocal about the need for users to be able to (1) choose what information they share with what companies and (2) undestand the tradeoffs they are making when they do.
Unfortunately, many online tracking practices, while potentially harmful to users, cannot be meaningfully understood or controlled by them.
Tracking by a first party – i.e., site or sites with which the user intends to interact and are operated by the same organization – are not an issue as the user can expect for their on-site behavior to be tracked by the company/organization. Mozilla wants users to be capable of preventing third-party tracking.
In its anti tracking policy, Mozilla singled out cookie-based cross-site tracking, URL parameter-based cross-site tracking and the use of unintended identification techniques for the purpose of online tracking as problematic and, sooner or later, destined for the chopping block.
The policy also notes that Mozilla might implement measures to block any new tracking technique that may be discovered in the future.
