Firefox can generate fake browsing history to interfere with ad tracking network

2 min read

We know that most of the ads on the Internet are delivered according to user interests, provided that the ad network has tracked and identified users in advance. For the advertising network, they already know what I am interested in. There are also many ways in which the ad network can be tracked, either by reading the browser history or by analyzing the users through cross-site tracking. Cross-site tracking is based on the analysis of the pages that users have viewed based on cookies, and then analyzes the content of these pages to classify the user’s preferences.

To interfere with historical tracking and analysis of user preferences, Firefox and third-party developers are providing new features for generating fake records. When the user enables this feature, Firefox will generate hundreds of fake browsing records, and users can choose from a variety of categories such as a hypebeast, a filthy rich person, a doomsday prepper, or an influencer. These historical records can take days or longer to be tracked and analyzed by the ad network, and then the ad network can modify user interest preferences. The precise advertisements pushed by the ad network after completion are all selected by the user. Of course, the function itself does not block the advertisement but is used to disturb the advertisement.

Advertisements pushed by the ad network after the disruption may not be of interest to the user, and ultimately control the advertiser and prevent the advertiser from understanding you. Please note that if you want to directly block cookies from third-party websites, please open them directly in the privacy settings. This feature works better than fake records.
