Considering LibreWolf is just a hardened Firefox config preconfigured (for the most part) all three things you've mentioned are present.

And compared to UGC, you don't have to sideload an extension to get the Firefox add-on store working nor deal with Google's malicious fucking up of their browser to advance their business interests. Instead, you deal with the LibreWolf team compensating for Mozilla's ineptitude and smug retardation.
