The real question is whether this sets a precedent for how browsers should handle feature creep in general. Browsers have quietly accumulated telemetry, sponsored content, pocket integrations, VPN upsells — AI is just the latest.

What I like about Mozilla's approach here is the single toggle for all current and future AI. That's a genuine concession to user agency rather than the usual whack-a-mole of about:config flags. If every new feature category got this treatment (a clear, discoverable off switch), browsers would be in a much better place trust-wise.

The deeper issue is that Mozilla needs revenue diversification beyond the Google search deal, and AI features are their bet on that. So the incentive to make the toggle hard to find or slowly degrade the non-AI experience will always be there. I'd love to see them prove that wrong.
