uBlock Origin Lite (Manifest V3) by Gorhill

uBlock Origin is a free, open-source browser extension designed for content filtering, primarily to combat privacy invasion while being efficient in CPU and memory usage. Developed by Raymond Hill in 2014, it originated from a fork of the HTTP Switchboard codebase and was initially released as a Chrome and Opera extension. By late 2015, it expanded to other browsers, gaining significant popularity due to user demand for effective ad-blocking solutions that operate outside the "acceptable advertising" framework used by other extensions. As of 2024, uBlock Origin is available on major browsers including Chrome, Firefox, Microsoft Edge, Opera, and older versions of Safari. The extension has amassed millions of active users, with over 5 million on Firefox and more than 10 million on Chrome. It is recognized for its potential to save consumers over $1.8 billion annually and is noted for its role in energy conservation. The project remains actively developed by Hill, with a focus on community-maintained block lists. uBlock Origin does not accept donations, instead encouraging users to support block list maintainers. The extension is licensed under GPL-3.0 and continues to be a leading choice in the ad-blocking industry, reflecting a commitment to user privacy and efficient browsing.
