Keeping your browser up to date is essential for Internet security. Mozilla Update Firefox regularly to cover any emerging threats. Updates are free, so you can install and keep them safe.
Update manually in Windows
If you want to see if there’s a Firefox update on your Windows computer, open Firefox. Click the hamburger icon (the three horizontal lines) in the upper right corner.
Click «Help» at the bottom of the list.
On the Help menu, click «About Firefox.»
The «About Mozilla Firefox» window appears. Provides information about the current version of Firefox running on your computer. If you have the latest version, you will see «Firefox is updated» in this window.
Otherwise, you’ll see a «Check for Updates» button. If a background update has already been uploaded, you’ll see the «Restart to update Firefox» button.
Click any of them to allow Firefox to load or install the latest update.
After restarting Firefox, click Help> About Firefox again to make sure you have the latest version now.

If you want to update Firefox on a Mac, open your browser. Click «Firefox» in the menu bar at the top of the screen, and then select «About Firefox.»
A window will appear with information about the current version of Firefox you are running on your Mac. If your browser is up to date, you’ll see «Firefox is up to date» in this window.
Otherwise, you’ll see a «Check for Updates» button. If a background update has been uploaded, you’ll see a «Restart to update Firefox» button.
Click any button to allow Firefox to load an update or restart.

Enable automatic updates
By default, Firefox updates automatically, but you can turn it off. It may be a good idea to check the update settings and make sure that automatic updates are enabled.
To do this, open Firefox and click the hamburger icon (the three horizontal lines) in the upper right corner.
In 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 «Automatically install updates» is selected.
In this menu, you can also click «Check for updates» to check manually.
From now on, Firefox will automatically update every time Mozilla releases a new version. Now you can rest assured that you will receive the latest bug fixes as soon as possible.
