This feels less like an “anti-AI” stance and more like a trust and control issue. For browsers especially, users have very different threat models and performance expectations, and “always on” AI features blur that line quickly. An explicit opt-out makes sense, but I wonder if the more important question is whether these features can be implemented in a way that’s truly local and auditable. If users can’t clearly understand where data goes and what runs on-device, toggles become a necessary safety valve rather than a preference.

I haven't paid close attention, but as far as I can tell, Mozilla has mostly invested in local AI for tasks such as translation, summarization, and organization. As long as that's the case, I don't see any particular safety or privacy risks; if it works without an Internet connection, it's probably OK.

Summarization is using a chosen cloud-based AI provider.

Are you sure? I see a huge spike in CPU when I long-click on a link to see the preview and summary. This is the newest summarization feature, not the older one with the chatbot on the side.

Ah, didn't know they moved to local models. My comment was about the old chatbot-based feature.
