Firefox is a web browser developed by Mozilla, using the Gecko rendering engine rather than Chromium. It is designed for everyday browsing, with an emphasis on user control, privacy and compatibility with modern web standards.
Its interface can be adapted to different workflows, from a minimal single-window layout to research sessions with many open pages. It also includes tools for working with documents and media without constantly switching applications.
Firefox supports bookmarks, history and password synchronisation through a Mozilla account. Its extension ecosystem allows users to add functionality, while its built-in tools serve both general users and web developers.
This is free and open source software.
