There is a repository available for Debian Unstable, which can be installed using the .deb file found on the Linux releases page, or from the Open Build Service, where there are also instructions for installing the repository manually.
Note: This is for Debian Unstable only - do not try to install this package on any other branch of Debian or Ubuntu/Mint, or you will have errors about being unable to resolve the dependencies.
See the LibreWolf Gentoo repo.
The LibreWolf AppImages are found here. Choose the file that matches your system’s architecture (most modern computers use x86_64).
chmod +x LibreWolf-*.AppImage
to make it executable.
Set up Flatpak for your distribution (make sure to enable the flathub repository, as LibreWolf requires several dependencies from there). Then download the LibreWolf Flatpak file from here (choose the file that matches your system’s architecture - most modern computers use x86_64), and install it using
flatpak install LibreWolf-*.flatpak
Compiling from source is possible for most versions of LibreWolf, just head over to the relevant repository, clone it, and read the README.md. As LibreWolf is a community effort, people are trying out different things in different browser repositories. In general tho, most of the compilation issues come from creating the build environment, the actual compilation process by Firefox is standard and relatively straightforward.
