Scroll Anchoring in Firefox 66

Firefox 66 was released last week with a new feature called scroll anchoring, based on a new CSS specification. Scroll anchoring works to anchor the user to the content they’re looking at. As this content is moved by ads, screen rotations, screen resizes, or other causes, the page now scrolls to keep you at the same relative position to it. Learn how our intervention works.
