§ Abstract
Summary
Browser reader modes improve user experience by stripping away clutter and presenting article content in a clean, distraction-free format. However, existing reader modes are implemented as extensions or built-in features that run in the same privilege context as the web page, exposing users to tracking and side-channel attacks. We present SpeedReader, a reader mode that is both fast and private by design. SpeedReader runs the reader mode feature in a separate, minimal rendering context that isolates the parsed article content from the original web page's scripts and trackers. Our evaluation shows that SpeedReader reduces third-party tracking by 89% compared to standard reader modes while maintaining rendering fidelity.
