How to Update Firefox Browser - Firefox

Open Firefox, click the menu button (three horizontal lines) in the top right corner, then select Help > About Firefox to check for and install updates automatically.

Firefox handles updates like a champ. The browser checks for new versions regularly and downloads them in the background. Most of the time, you won't even notice it's happening. When an update is ready, Firefox prompts you to restart the browser to complete the installation.

That's seriously it!

Manual Update Method

Want to take control? Go to the menu button > Help > About Firefox. This page shows your current version and scans for updates immediately. If a newer version exists, Firefox downloads it right there. You'll see a blue "Restart to Update Firefox" button once it's ready.

Click it, and you're done in seconds. The restart is quick — you won't lose your open tabs.

Why Keep Your Browser Current

Updates matter more than you think. Mozilla releases patches for security vulnerabilities, performance improvements, and new features regularly. Running an outdated version leaves you exposed to potential threats. Firefox 148.0.2 and newer versions include enhanced privacy protections and faster rendering.

Staying up to date keeps your browsing safe and smooth.

Automatic Updates Enabled by Default

Here's the thing — Firefox automatically updates itself on most systems. You don't need to do anything. Check Settings > General > Firefox Updates if you want to verify automatic updates are on. The browser can also update while it's closed, so new versions install silently overnight.

Running Firefox on Windows, macOS, or Linux? The update process works identically across all platforms. The free, open-source browser makes staying current effortless.

Pro tip: restart Firefox weekly to ensure any pending updates install. Takes seconds and keeps your browser in peak condition!
