Mozilla Firefox Overview

Mozilla Firefox is a Free (MPL) web browser available for Windows and macOS and Linux from Mozilla Foundation. The Mozilla Firefox v130.0 offline installer is a complete standalone setup file — every rendering engine component, extension framework, and security module is packed into a single 55 MB download that installs without any internet connection. Unlike a web installer or stub downloader that pulls files during setup, the Mozilla Firefox standalone setup works completely offline once downloaded. The Mozilla Firefox standalone installer also makes it easy to keep an archived copy for future reinstalls or rollback scenarios. Download the Mozilla Firefox full setup from the official Mozilla Foundation page and get a clean, trusted installation with no bundled adware.
