How to Update Firefox - Firefox

Firefox automatically updates itself by default, but you can manually check for updates anytime through the Help menu.

Check for Updates Manually

Open Firefox and click the menu button (three horizontal lines) in the top right corner. Select "Help" then "About Firefox." The browser immediately scans for available updates and installs them automatically if found. You'll see the current version number here too — Firefox 148.0.2 is the latest. The whole process takes just a few seconds!

Let Updates Happen Automatically

Firefox handles most updates without you doing anything. When a new version releases, Firefox downloads it in the background while you browse. You'll get a notification asking to restart the browser to finish the installation. Just close Firefox normally, and when you reopen it, you're running the newest version.

No interruptions. No hassle.

Why Keep Firefox Updated

Updates aren't just about new features. They patch security vulnerabilities and fix bugs that could slow down your browsing. Since Firefox launched back in 2002, Mozilla has prioritized user privacy and security — and regular updates are part of that commitment. The free, open-source browser gets better with each version.

Pro Tip

You can customize update preferences in Firefox settings if needed. Head to Settings > General > Firefox Updates to adjust whether Firefox updates automatically or just notifies you. Most users leave it on automatic — it's the safest approach.

How to update Firefox really comes down to letting the browser do its job. Whether you're on Windows, macOS, or Linux, the process is identical and painless. Just keep Firefox running normally, and those updates roll in automatically!
