You can also install Firefox through the Flatpak option.

Flatpak is a new packaging format for Linux. To setup Flatpak, visit FlatPak's setup guide and select your OS and follow the installation steps.

Once you have Flatpak installed, go to the Firefox Flathub page and click the button. Once downloaded, follow the command line instructions at the bottom of the page.

Once Firefox is installed from Flatpak, updates are automatic so no need to reinstall.

Download a specific locale version

When installing Flatpak (via the command line or via the Flathub url link), the OS locale is being checked (OS locale and not the browser accept language header) and Flathub only sends the locales that share the same prefix. So for example if LANG=en_US.UTF-8 Flatpak will send locales that have the common prefix en which are en-CA, en-GB etc.

To download a specific locale it can be done manually. For example, specific installation of French (fr) locale:
flatpak update --subpath=/fr org.mozilla.firefox.Locale

To install Firefox using the package manager, please refer to your Linux distribution's documentation.

The support sites for some Linux distributions have complete instructions on how to install Firefox without using a package manager, although a few information may be out of date. For example:
