How to update Firefox

On your computer

1. Click the menu button (three lines) at the right end of the toolbar.
2. Choose Help, then About Firefox. On a Mac you can also use the Firefox menu in the menu bar, then About Firefox.
3. The small About window checks for updates and downloads any update by itself.
4. Click Restart to Update Firefox. Your tabs come back after the restart.

Official Firefox instructions

On Android

1. Open the Firefox page in Google Play with the button below — the store lists it as “Firefox Fast & Private Browser”, which is the same app.
2. If you see an Update button, tap it. If you see Open instead, you are already up to date.
3. No luck? In the Play Store, tap your profile picture at the top right, choose Manage apps & device, and update Firefox from there.

Open Firefox in Google Play

On iPhone and iPad

1. Open the App Store.
2. Tap your profile picture at the top right.
3. Scroll down to the list of available updates.
4. Tap Update next to Firefox, or Update All.

On iPhone and iPad, every browser uses the web engine that ships with iOS, so it also helps to keep iOS itself up to date: Settings, then General, then Software Update.
