Tracking Protection arrived with Firefox 42 last November, giving users control over what types of data third parties received from their browsing. This could mean certain online advertisements might not display properly.
However until now, Tracking Protection has been limited to private browsing. Mozilla is looking at extending this protection to all tabs but first needs to see where the feature “breaks” the web – this includes ads.
To achieve this, it is inviting users to participate in a ‘Test Pilot’, a scheme which sees Firefox users test experimental features in the early stage of development.
