It's important to keep up with the latest version of Firefox. The browser is updated frequently, and each revision squashes bugs, improves security, and sometimes introduces new features. 

If you want to make sure you're running the latest version of Firefox, the process is similar whether you are using Windows or a Mac. By default, Firefox checks for updates and installs them automatically. But if you want to make sure the latest update is installed right away, you can do it with a few clicks.

How to update Firefox on Windows

1. In the Firefox browser, click the three-line menu at the top right of the screen.

2. In the drop-down menu, choose Help, then About Firefox

3. In the Firefox pop-up window, you should see an update status message under the Firefox Browser title. If the browser is running the latest version, it will say Firefox is up to date. Otherwise, it will say Restart to Update Firefox. Click that to install the updates and restart the browser.
