Firefox is the default web browser in many Linux distributions, and Ubuntu is one of them. Firefox comes preinstalled on Ubuntu unless you are using Ubuntu's minimal version.

In this tutorial, I am going to show you how to install the latest version of Firefox on Ubuntu or any other Linux distribution.

Firefox is available for almost all the Linux distributions out there. It is also preinstalled in most of them.

If that’s not the case, you should stick to the official package manager provided by your distribution for installing Firefox. That’s the easiest and best method. It will be updated automatically to newer versions with system updates.

Open the software center and search for Firefox. You should see it there and just click on the installation button.

In Ubuntu, Firefox is a Snap. So installing it via APT package manager won't work. If you need that version of Firefox, you may follow our separate tutorial on how to remove snap from Ubuntu.

If you prefer the command line, open a terminal and use the following command in Debian, and other distributions based on Ubuntu and Debian such as Linux Mint, elementary OS etc.

sudo apt install firefox

Similarly, Fedora users can use dnf command, Arch users can use pacman and other package managers provided by the distribution.

sudo dnf install firefox
sudo pacman -Syu firefox

Once installed, just look for it in the menu and launch it.

Installing Firefox using Snap or Flatpak

Mozilla Firefox maintains both Snap and Flatpak packages. So, you can pick any of them in any Linux distribution.

If your software center supports Flatpak/Snap integration, you do not need to use the commands. If it does not, follow the commands for quick installation.

To install the Snap package, make sure that you have snap installed. Once done, enter the following command in the terminal (or search for it in your software center):

sudo snap install firefox

Similarly, you will have to install and configure Flatpak first. Once done, enter the following command to get it installed (or search for it in your software center):

flatpak install flathub org.mozilla.firefox

Installing Firefox from the Official Website

Another method that would work in any Linux distribution is to download the binary from the Firefox website and then use it for running Firefox.

It will take more time, but if it is something you prefer, you can follow the steps below:

  1. Remove Existing Firefox

Before installing another Firefox, it is good to make sure that you don't have any Firefox already installed. So, on Debian and other similar systems, use:

sudo apt purge firefox

Similarly, if you have Firefox Flatpak, it can be removed by using:

flatpak uninstall org.mozilla.firefox

On Ubuntu snap, first remove the snap version. Also remove any Firefox transitional packages.

sudo snap remove firefox
sudo apt purge firefox
  1. Download and Extract Firefox

Once the existing Firefox is removed, you can now download the Firefox files from the official website.

This will download the Firefox Tar file. To extract, open a terminal and use the following command on the directory where you downloaded it:

tar xjf firefox-*
  1. Setup Firefox

It’s a standard practice to use the /opt directory for keeping application files.

So, just to make sure that you don’t have a Firefox directory already in there, run the command below:

sudo rm -r /opt/firefox

Now, copy the extracted directory to /opt. For this, open a terminal on the location where you have the extracted Firefox directory and run:

sudo mv firefox /opt

To make it work, you need to create a symbolic link to the Firefox in /usr/local/bin.

ln -s /opt/firefox/firefox /usr/local/bin/firefox
  1. Create a Desktop File to Get an Icon on the System Menu

To access Firefox from your system menu, you need a desktop file. You can use the official format from Firefox.

You should have a directory called 'applications' in /usr/local/share/. If it's not there, first create one using sudo mkdir -p /usr/local/share/applications.

Open a terminal and run:

wget -P /usr/local/share/applications

Alternatively, you can download the desktop file by clicking on the button below. On the page, right click and select the “Save Page As” option. Save it as firefox.desktop.

Right-click on the page and select "Save Page As" option to save the Firefox Desktop File
Save the Page

Paste this firefox.desktop file to /usr/local/share/applications/.

That's it. You can now launch Firefox from the system menu.

From the top-right hamburger menu, go to Help and then About Firefox
Go to About Firefox

Click on the “Restart to update Firefox” button to update Firefox.

In the About Firefox window, click on "Restart to Update Firefox" button to update Firefox

You can check the About page for more.

On the About Firefox page, it will display a "Firefox is up to date" message, if you are running the latest version

Uninstall Firefox

Uninstalling Firefox installed through the website is pretty straightforward. Just retrace the path you have used. First remove the Desktop file and the symlink from their respective location.

sudo rm /usr/local/bin/firefox
sudo rm /usr/local/share/applications/firefox.desktop

Now, remove the Firefox directory from /opt.

sudo rm -r /opt/firefox

You have uninstalled Firefox.

Bonus: Install Firefox Nightly Version

If you want to experience the latest features before its final release, you can install the nightly version by downloading the respective binaries from the official website.

Nightly builds are supposed to be unstable and for testing purposes only.

You can follow the same method detailed in the previous section to install it.

For Debian and its derived distributions like Linux Mint, Pop!OS etc., Mozilla provides a PPA to install Firefox Nightly version. The major advantage is that, you will get a better performance, automatic updates and also a preconfigured desktop integration.

First, you need to create a directory to store APT repository keys if it doesn't exist, and then import the Mozilla APT repository signing key.

sudo install -d -m 0755 /etc/apt/keyrings

wget -q -O- | sudo tee /etc/apt/keyrings/ > /dev/null

Now, import the GPG key and add the Mozilla APT repository to your sources list.

gpg -n -q --import --import-options import-show /etc/apt/keyrings/ | awk '/pub/{getline; gsub(/^ +| +$/,""); print "\n"$0"\n"}'

echo "deb [signed-by=/etc/apt/keyrings/] mozilla main" | sudo tee -a /etc/apt/sources.list.d/mozilla.list > /dev/null

Once done, you can now update your package list and install the Firefox Nightly.

sudo apt update
sudo apt install firefox-nightly

Wrapping Up

Firefox is available in various formats to install in Linux. In most cases, Firefox should come baked in with the distribution of your choice.

If it is not there, you can search for it in the software manager or get the Snap/Flatpak builds.

If you are an Ubuntu user, sticking with the default Snap version, using the pre-built binary from Firefox or Firefox Flatpak is recommended.
