Mozilla Firefox is a free, open-source web browser built on Mozilla's Gecko engine. Its Awesome Bar searches browsing history, bookmarks and open tabs as a user types, while tabbed browsing keeps multiple sites in one window. App Tabs pin frequently used pages, and Switch-to-Tab directs users to an already-open site. Panorama groups tabs visually, and Firefox can reopen recently closed tabs or windows.

Mozilla Firefox is a free, open-source web browser for people who want to visit websites, manage bookmarks and keep several pages open in one window. It uses the Gecko engine to display web pages and supports web standards. Firefox is developed by Mozilla, a nonprofit organization focused on an open web, with contributions from a worldwide community and support for many languages.
The location bar, called the Awesome Bar, helps find sites without needing to remember their full addresses. As a user types, it suggests matches from browsing history, bookmarks and open tabs; its suggestions adapt to browsing habits, and privacy settings provide control over results. Tabs let people move between multiple sites in a single window. App Tabs keep frequently used sites, such as webmail, in a compact, persistent spot, while Switch-to-Tab finds an existing page when its address is entered again, avoiding duplicate tabs.
The interface groups common controls for navigation and organization. A combined stop and reload button handles pages that are loading or need refreshing, and dedicated bookmark and home controls make those actions easy to reach. On Windows and Linux, the Firefox button brings menu items together. For people with many open pages, Panorama provides a visual way to arrange tabs into named groups: tabs can be dragged between groups, which can be organized and revisited as needed. Recently closed tabs and windows can also be reopened after an accidental closure.
These tools suit everyday browsing as well as research and work that involves moving between many websites. History and bookmarks make previously visited pages easier to find, while tab groups can separate topics or tasks. App Tabs are useful for sites that stay open throughout a session, and Switch-to-Tab helps keep a crowded window from filling with repeated pages.
Firefox is distributed as freeware and open-source software. The supplied system information names Windows XP, Vista, 7 and 8, including some 64-bit editions; it does not establish support for Windows 10 or 11. The installer size is approximately 20 MB. This browser is intended for web browsing on Windows, with equivalent Firefox products also available on other platforms.
