Mozilla’s Mission Nova redesign provides a single Settings management to disable all AI options in Firefox.
Courageous launched Courageous Origin in April, a $60 one-time buy (free on Linux) that compiles out AI, Pockets, Rewards, and telemetry solely.
Chrome not too long ago eliminated its disclosure promising to maintain Gemini Nano information off Google’s servers, including gasoline to the AI-in-browsers backlash.
The browser wars simply bought a twist: As a substitute of cramming extra AI down your throat, Firefox is including a change to show all of it off.
Mozilla unveiled Mission Nova on Might 21—a full visible overhaul of Firefox rolling out later this yr. The redesign is cleaner, hotter, and sooner, that includes rounded tabs, a refreshed colour palette impressed by fireplace, and compact mode lastly making a comeback. However the headline function for a rising slice of customers is not the aesthetics.
It is an anti-AI change.
Mozilla is redesigning its settings with plain-language controls that make privateness decisions simpler to behave on—together with, per the official announcement, “controls for turning off AI options solely.” No buried menus. No darkish patterns. Simply an off button.
It additionally comes with a graphic replace, meant to make the brand new technology of Firefox browsers look rather a lot higher.
Picture: Mozilla
The timing could not be higher. Chrome has been quietly putting in an undeletable 4GB Gemini Nano mannequin on its customers’ PCs. In the meantime, browsers like Dia, Opera Neon, and Comet have been racing to construct AI-first experiences that automate shopping and chat along with your tabs.
Seems not everybody desires that.
Courageous seen the identical backlash. In April, the corporate launched Courageous Origin—a paid browser construct (one-time $60, free on Linux) that strips out every thing: Leo (its AI assistant), Rewards, Pockets, VPN, Tor home windows, and telemetry. Gone. The browser makes use of Privateness Go blind token know-how so the $60 buy is not even tied to your gadget identification.
The concept got here from actual demand: tutorials on manually “debloating” Courageous had been going viral for years. Courageous simply packaged the method and charged for it.

The truth that “no AI, no bloat” is now a paid product class says one thing.
Firefox’s method is subtler. Mozilla is not abandoning AI options—its free built-in VPN and summarization instruments stay choices. Mission Nova merely bets that giving customers seen, sincere management is a differentiator in 2026. “Firefox remains to be the one browser constructed for individuals, not platforms,” Mozilla stated in its announcement.
That may learn to some as a calculated jab at Chrome, which holds roughly 66% of world browser market share whereas working AI fashions within the background—with or with out specific consent from customers. Firefox has been dropping market share for years, sitting at round 4.44% way back to 2020 with no main reversal since.
Making “off by default” a function is perhaps a raffle—but it surely additionally is perhaps probably the most sincere pitch within the browser market.
