As you browse the web, your browsing behavior may be observed and aggregated by third-party websites ("trackers") that you don't visit directly. These trackers are generally embedded by host websites in the form of advertisements, social media widgets (e.g., the Facebook "Like" button), or web analytics platforms (e.g., Google Analytics).
TrackingObserver is a Chrome extension that acts as a platform for detecting, measuring, and blocking third-party web trackers. Unlike other tools, TrackingObserver does not use a blacklist of known tracking domains, but rather detects trackers automatically based on their in-browser behaviors (such as setting and receiving third-party cookies).
Different trackers exhibit different behaviors, which give them different capabilities. For example, some trackers can track you only when you return to the same site, while others can track you as you browse multiple different sites. TrackingObserver automatically categorizes trackers according to the taxonomy described at http://trackingobserver.cs.washington.edu/.
TrackingObserver is not just a stand-alone Chrome extension, but a platform. It exposes APIs for tracking detection, measurement, and blocking, and you can install or develop add-ons that provide visualization or other functionality. TrackingObserver prevents add-ons from needing to reinvent or reimplement its automatic tracking detection algorithm, while allowing them to innovate in other ways.
We hope that TrackingObserver will be valuable for users, developers, and web tracking researchers.
Extore is a team of professionals who are passionate about creating extensions for web browsers. This devotion also gives us opportunity to appreciate work of other people. We get inspired by useful, open source extensions made by developers all over the world. Our strong belief is that one should share helpful add-ons with others. That’s why we’d like to present you our ever-growing list of favourite extensions that have inspired us. Moreover, as you probably have already learned, sometimes struggling for the best brings an end to the good. Talking about add-ons it often turns out that an upgrade is worse then previous version. Also it can become really tricky to get back to the beloved version of your favourite extension. That’s why we’re going to make not only the latest, but all versions of our favourite (and we hope yours too) add-ons available for download. No more compromises, just stick to the version you really like!
