To install LibreWolf on any other Linux Distribution, you have three options

Flatpak

If your distribution doesn't include it by default, check out Set up Flatpak to find out how to install it.

To add the Flathub repository, use:

flatpak remote-add --if-not-exists flathub https://dl.flathub.org/repo/flathub.flatpakrepo

NOTE: You can also restrict the repository, for example "only free libre open source" or "only verified apps". The Librewolf Flatpak is verified, so you can use the subset:

flatpak remote-add --subset=verified flathub https://dl.flathub.org/repo/flathub.flatpakrepo

# or when already added, check if all your apps are verified, or they don't get updates!
flatpak remote-modify --subset=verified flathub

# to remove the subset:
flatpak remote-modify --subset= flathub

To install from Flathub:

flatpak install flathub io.gitlab.librewolf-community

For running it, you can find it in the app menu, or use

flatpak run io.gitlab.librewolf-community

Make sure to set it as default browser in the system settings, as the Flatpak is not allowed to access them.

Security

Flatpak apps run sandboxed from the system via bubblewrap, which adds a layer of protection. But this prevents the browser from using its usual sandbox for process isolation.

Processes are still isolated through nested seccomp filters.

Flatpak supports process isolation via flatpak-spawn, which zypak and the unofficial Chromium Flatpak use. This would cause a big increase in memory use in Firefox/Librewolf though, so it is not a viable solution.

AppImage

Download LibreWolf-128.0-2.x86_64.AppImageView all versions and release notes

Installing

To install LibreWolf permanently via an AppImage, we recommend AppImageLauncher.

With AppImageLauncher installed, you just need to open the AppImage with AppImageLauncher and click Integrate and run. LibreWolf should then be permanently installed on your system and launchable via the application menu.

Updating or Uninstalling

To update or uninstall LibreWolf from your system, you can just right click the LibreWolf application menu entry and click either Remove AppImage from system or Update AppImage.

After pressing the update button, the whole update process will be completely automatic and you don't have to do anything else.

Compiling from source

To compile LibreWolf from source, you can take a look at the README.md in the source repository.
