Mozilla Firefox ESR

Mozilla Firefox ESR is a free internet browser for MacOS. It belongs to the Internet & Browsers category. The software is intended for people who use a MacOS computer to access websites and online services. Its role is to provide a browser application that can be installed and used on that platform.

The product is distributed through MirrorNest as the official build. MirrorNest mirrors that build directly on its own storage rather than presenting a separately described version. This gives readers a straightforward source for obtaining the listed software. The available license is free, so no purchase is required to use the product under the terms provided here.

Before publishing the mirrored file, MirrorNest scans it for malware. This scanning step is part of the catalog’s distribution process and does not change the stated product or license. The MacOS platform designation helps users determine whether the software matches their computer. Its placement in Internet & Browsers identifies it as software for general web access rather than a different type of application.
