I’m not a contributor to LibreWolf so I can’t speak with authority on it but I can’t imagine that they are so different from Firefox that they wouldn’t be able to just merge 99% of updates from FF with minimal effort.
From looking at the repo, it looks like it’s simply a set of patches that get applied to the Firefox source code. They don’t maintain a fork, just a set of changes that get applied before building.
