Install latest versions of Firefox from Mozilla

Open Terminal and copy and paste below commands into it:

  • Add repository:
sudo tee /etc/apt/sources.list.d/mozilla.list << EOF
deb mozilla main
  • Download the key:
wget "" -O mozilla.key
  • Convert it to gpg:
gpg --no-default-keyring --keyring ./mozilla_keyring.gpg --import mozilla.key
gpg --no-default-keyring --keyring ./mozilla_keyring.gpg --export > ./mozilla.gpg
  • Move it to the apt folder:
sudo mv -v mozilla.gpg /etc/apt/trusted.gpg.d/
NOTE: You can remove the mozilla_keyring.gpg file from your home directory after that.
  • Update package list to include new sources and install Firefox browser:
sudo apt update && sudo apt install firefox

To install a language pack:

sudo apt install firefox-l10n-XX

Replace XX with language code, for example: fr for French.

NOTE: You can also install testing/nightly version, but these are considered unstable.

The default Firefox package from PureOS: firefox-esr (ESR stands for Extended Support Release) can coexist with the latest version you will install from Mozilla, as it is using separate user profile. You can remove the "ESR" version later:

sudo apt remove firefox-esr firefox-esr-l10n-*

If you want to import your bookmarks, passwords, and other data from your "ESR" profile to the new Firefox version, you can follow the official guide from Mozilla website.
