Microsoft introduced today a new feature to its new Chromium-based Edge browser that it calls Tracking Prevention.
As the name implies, the new feature can be used to block tracking scripts loaded by aggresive online advertisers and web analytics firms.
The feature is currently only available in Microsoft Edge Insiders preview builds. Microsoft says the feature still needs work, but it’s rolling it out in the current in-dev stage so it can get useful feedback from users and accelerate its development.
How Tracking Prevention works
Tracking Prevention is eerily similar to the Enhanced Tracking Protection feature that Mozilla added to Firefox last year, and turned on by default for all users this spring.
The two work in a similar way. When enabled, they will block tracking scripts loaded from domains the user isn’t accessing directly, such as those loaded from ad slots, by analytics services, and more.
But the mechanism is a little bit more complex….
