Mozilla Firefox ESR (Extended Support Release) is a version of the Mozilla Firefox web browser designed for use in organizations and enterprises. It provides a stable and extended support cycle, with security updates and maintenance over an extended period. It is ideal for businesses and institutions requiring a reliable and secure web browsing experience. Mozilla Firefox ESR Portable is also available.

Mozilla Firefox is a high-speed, fully-featured web browser known for its user-friendly interface. It offers an array of impressive features, including efficient popup-blocking, convenient tabbed-browsing, seamlessly integrated search capabilities, enhanced privacy features for secure browsing, automatic updating to ensure the latest security patches and improvements, and much more.

Mozilla Firefox ESR (Extended Support Release) is specifically tailored for organizations that need a more controlled and stable browser deployment. It provides a separate release schedule and version from the standard Firefox Stable version. This ESR is particularly beneficial for large organizations such as universities, schools, government entities, businesses, and the developers who support them. The ESR version ensures long-term support and stability for the desktop environment, making it ideal for deployment and maintenance in these settings.

The standard Mozilla Firefox, for example, is recommended for individual users who do not require the specialized features and support offered by the ESR version.

This Mozilla Firefox Extended Support Release (ESR) includes all of the enhancements since Firefox 128, along with many new features to make your enterprise deployments easier and even more flexible.
