thornbird

Thornbird is a free and open-source web browser developed by the Mozilla Foundation, the same organization behind the popular Firefox browser. It is designed to be a lightweight, privacy-focused alternative to mainstream browsers, emphasizing speed, security, and user control. Thornbird is built on the same core technology as Firefox, including the Gecko layout engine and Quantum rendering engine, which provide efficient and modern web browsing experiences.

The browser is named after the thornbird, a mythical bird from various folklore traditions, symbolizing resilience, adaptability, and a connection to nature. Thornbird was initially released as an experimental project in 2020, aiming to offer a stripped-down version of Firefox with fewer default features to reduce bloat and improve performance. It is distributed under the Mozilla Public License (MPL), ensuring transparency and community collaboration in its development.

Thornbird includes several privacy-enhancing features, such as built-in ad and tracker blocking, enhanced HTTPS enforcement, and a focus on minimizing telemetry data collection. It also supports extensions and customization, allowing users to tailor their browsing experience. The browser is available for Windows, macOS, and Linux, with regular updates to address security vulnerabilities and improve functionality.

Unlike Firefox, Thornbird does not include certain default components like the Firefox Account sync or some built-in add-ons, making it a more minimalist option for users who prioritize simplicity and control. The project remains in active development, with contributions from the open-source community shaping its future direction. Thornbird is suitable for users seeking a fast, private, and lightweight browser without unnecessary features.
