There is a crucial difference between a config file that changes options within Firefox, and something that adds new code. Unless something has changed dramatically, the Firefox team (and other teams) test and fuzz Firefox extensively - obviously default prefs and features will get more coverage. An actual fork like LibreWolf that adds or removes code and ships a different build fundamentally changes how the software is built and invalidates a significant portion of the security work that has been done by the Firefox security team. I am not arguing that Librewolf or any of the other forks of Firefox[1] are necessarily worse for security, just that browsers are ridiculously complex pieces of software and making claims about security requires more than just gutting or adding features. [1] other than Palemoon, because screw those guys; when I challenged them on the security program for Palemoon, their loopy leader tried to harass me and other former Mozilla folks. Given their propensity for instability I wouldn't trust them at all.
