Firefoxselaimen

Firefoxselaimen, known in English as the Firefox browser, is a free and open-source web browser developed by the Mozilla Foundation. It emphasizes user privacy, security, and customization and is available on Windows, macOS, Linux, Android, and iOS.

Its engine uses Gecko, with major performance improvements from the Quantum project introduced in 2017, delivering faster page rendering and a more responsive user interface.

Key features include a multi-process architecture, Enhanced Tracking Protection, private browsing mode, and extensive add-on support via WebExtensions. Users can sync passwords, bookmarks, and preferences across devices through a Firefox account.

Firefox is open-source, allowing independent security audits and community contributions. It provides built-in security measures such as phishing protection, TLS support, and frequent security updates.

In the browser market, Firefox remains a major non-Chromium option and is particularly valued by privacy-conscious users. It competes with other engines and emphasizes openness and interoperability.
