I know public sentiment for AI is not great right now, but personally I don't see a problem with it and I like that Firefox is adding it, especially because it's not in your face the way other browsers have it.
I recently switched to Firefox from Edge because the AI push was too great with Copilot (and I thought that even though I was one of the few people who actually enjoyed using Copilot)
I immediately liked that Firefox let me pick from multiple different cloud provided AI models and I'm not stuck with using whichever one you pick for me.
I've started self-host my own local LLM server using Ollama and OpenWebUI, and I think it'd be great if I could select my own models to be used in Firefox from the list instead of just the major cloud provided ones.
Obviously not a priority feature, but something to think about nonetheless.
