Mozilla is testing new privacy setting in Firefox. Here, the browser should not leave traces of user activity on a computer: no copies in the cache, no traces of your browsing history and cookies. The new privacy settings Firefox blocks online services that try to track the movement of the user on the Web pages and display contextual advertising.
Thus, Firefox natively does what developed extensions to the browser like Ghostery and Privacy Badger from the Electronic Frontier Foundation.
Experimental feature tested in version for developers of Firefox Developer Edition for Windows, Mac and Linux, as well as on Channel Firefox Aurora for Android.
The new feature works so well that in reality, blocking even a significant portion of advertising banners. Instead, they displayed the inscription “Advertisment”.
Naturally, advertisers and representatives of the media industry will be unhappy, if such a new privacy settings will go into the final release of Firefox. There is a high probability that the Mozilla will have to rethink the algorithm lock tracking online services, because now it is too effective.
“We assume that if you open a window in the privacy settings in Firefox, then this is a clear signal that you want better control of their sensitive information than it provides normal mode browser” – Firefox developers wrote in the official blog.
