Enterprise-grade protection, powered by Firefox

Your browser, your business

Firefox combines open-source transparency with advanced security features and frequent updates to help safeguard your organisation’s data.

Deploy when and how you want

With install packages and a wide expansion of group policies and features, deployment is faster and more flexible than ever — and a breeze for Windows, Linux and macOS environments.

Release cycles that fit your organisation

Choose Firefox for the latest features and stable releases every four weeks, or Firefox ESR for long-term stability, regular security updates and annual major releases.

Support for Organisations documentation

Support for Organisations is a dedicated offering for teams who need private issue triage and escalation, defined response times, custom development options, and close collaboration with Mozilla’s engineering and product teams.
