Installation instructions for

LibreWolf for Arch Linux can be downloaded from the AUR. There there are two packages, librewolf and librewolf-bin. The first one compiles Librewolf from the Firefox source code with our patches and modifications while the second one provides a binary.

With yay

yay -S librewolf

or alternatively

yay -S librewolf-bin

Without an AUR helper

git clone librewolf
cd librewolf
makepkg -si

Note The since the librewolf version compiles the whole browser from source, the installation will take a long time. For a fast installation, librewolf-bin is recommended.
