Tracker Blocker for Chrome

What Are Trackers?

Trackers are third-party JavaScript files loaded by websites that monitor what pages you visit, how long you stay, what you click, and what you search for. This data is sent to data brokers and ad networks to build behavioral profiles used for targeted advertising.

Common trackers include Google Analytics, Facebook Pixel, Hotjar, Mixpanel, Segment, DoubleClick, and hundreds of lesser-known analytics and advertising SDKs.

How ProBlocker Blocks Trackers

ProBlocker uses the EasyPrivacy filter list and supplementary tracker blocking lists. When a website tries to load a tracker script from a known tracking domain, ProBlocker cancels the request before it reaches the tracker's server. The tracker never runs, never receives your data, and never adds your visit to your profile.

Does Blocking Trackers Break Websites?

Most websites function normally without tracker scripts — these scripts serve the website's analytics and advertising needs, not users. In rare cases, a site may have core functionality tied to a tracking service (for example, a site that uses Google Analytics for A/B testing of page load). ProBlocker's whitelist feature lets you re-enable on specific sites if needed.
