WARNING: Beta versions may contain bugs and cause your system to become unstable!
The award-winning Web browser is better than ever. Browse the Web with confidence. Firefox protects you from viruses, spyware and pop-ups.
Enjoy improvements to performance, ease of use and privacy. It's easy to import your favorites and settings and get started.
The latest version delivers easier navigation for everyone, including those who are visually or motor-impaired. Firefox is the first browser to support DHTML accessibility, which, when enabled by Web authors, allows rich Web applications to be read aloud. Users may navigate with keystrokes rather than mouse clicks, reducing the tabbing required to navigate documents such as spreadsheets. Firefox is also the first browser to meet US federal government requirements that software be easily accessible to users with physical impairments.
