Firefox
A privacy-focused browser with tracker blocking and cross-device sync.
Firefox is Mozilla’s web browser for desktop and mobile, built around privacy controls, customization, and independence from ad-driven data businesses. It includes automatic tracker blocking, browser extension support, tab and reading tools, PDF editing, and encrypted syncing of tabs, history, and passwords across devices.
Why it stands out
- Run by Mozilla rather than a shareholder-owned ad platform, with an explicit stance against selling personal data.
- Privacy protections are enabled by default instead of depending mainly on add-ons or manual configuration.
- Large add-on and theme ecosystem, with more than 30,000 extensions noted on the page.
- Works across desktop, mobile, and tablet while keeping synced browsing data encrypted.
- Includes migration tools for bringing bookmarks, passwords, and history from another browser.
Good to know
- Current Firefox is no longer supported on Windows 8.1 and earlier; those users are directed to Firefox ESR.
- Current Firefox is no longer supported on macOS 10.14 and earlier; those users are directed to Firefox ESR.
- Some cross-device benefits depend on using Firefox across multiple devices rather than only as a single-device browser.
