That thread is several months old, and is specifically about integrating Arkenfox settings changes. I wouldn’t say Librewolf has ceased development based on the fact that their default settings differ from Arkenfox. Their Codeberg site shows ongoing work.
Llamacpp, Koboldcpp, and TabbyAPI are also popular local backends for local AI. SillyTavern or RisuAi are good frontends for a chat/RP style experience. Or LM Studio for a simple, all in one solution.
