Manually Update on Windows
If you want to see if there’s an update for Firefox on your Windows computer, just open Firefox. Click the hamburger icon (the three horizontal lines) in the top-right corner.
Click “Help” near the bottom of the list.
In the Help menu, click “About Firefox.”
The “About Mozilla Firefox” window appears. It provides information about the current version of Firefox your computer is running. If you have the latest version, you’ll see “Firefox Is Up to Date” in this window.
If not, you’ll see a “Check for Updates” button. If an update has already loaded in the background, you’ll see a “Restart to Update Firefox” button.
Click either of these to allow Firefox to load or install the latest update.
After Firefox restarts, click Help > About Firefox again to make sure you now have the latest version.

Turn on Automatic Updates
By default, Firefox automatically updates itself, but you can disable this. It might a good idea to check your update settings and make sure automatic updates are enabled.
To do so, open Firefox and click the hamburger icon (the three horizontal lines) in the top-right corner.
On Windows, click “Options”; On a Mac, click “Preferences.”
When the Options (Windows) or Preferences (Mac) tab opens, scroll down to the “Firefox Updates” section. Make sure the radio button next to the “Automatically Install Updates” option is selected.
In this menu, you can also click “Check for Updates” to manually check.
From now on, Firefox will automatically update any time Mozilla pushes a new release. You can now rest easy knowing you’ll receive the latest bug fixes as soon as possible.
