The websites on the internet track your activity and create your profile so that they can serve you targeted ads. Firefox browser here comes as a savior. Now Firefox allows you to block the tracking content on the websites without using any third party add-ons.
How Does Content Blocking Works on Firefox?
Firefox started blocking content to protect the privacy of users. Several websites collect user’s personal information like their interest, activity, likes, and dislikes, etc. This information is later used to serve targeted ads on your browser. They also sell it to other advertisement companies. Mozilla joined their hands with Disconnect, a privacy concern company to start blocking such content.
Disconnect classifies the trackers that collect information with the intent to use it later or share it with third-party clients. Such trackers are flagged and blocked. However, the trackers that collect information only to improve the user experience are allowed. Meaning when a tracker collects information and store it in a database, such trackers are blocked.
Firefox has categorized the content blocking in three modes that let you choose according to your need.
- Standard – It is the default mode and only blocks the trackers that are harmful. It tries to create a balance for performance and protection. The Standard mode allows some trackers that are essential for the websites to function properly. It blocks the known trackers in the private window.
- Strict – This mode blocks all the trackers. It helps you to attain stronger security. However, some websites may not work correctly. It blocks known trackers, third-party tracking cookies, cryptominers, fingerprinters in all window.
- Custom – In this mode, you can choose what to block according to your need. You can select between trackers, cookies, cryptominers, and fingerprinters.
Note:- Blocking all cookies or all third-party cookies may cause websites to break. Some parts may not load properly if you block the cookies.
