Firefox Project Nova redesign adds toggle to disable all AI features
In brief
- Project Nova redesigns Firefox with rounded tabs and a fire-inspired color palette.
- Plain-language controls let users disable AI features entirely, giving explicit choice over integration.
- Mozilla's approach contrasts with Chrome's quiet installation of a 4GB Gemini Nano model.
The redesign: rounded tabs and fire
Project Nova features rounded tabs, a refreshed color palette inspired by fire, and compact mode finally making a comeback. Mozilla is redesigning its settings with plain-language controls that make privacy choices easier to act on—including controls for turning off AI features entirely.
The timing is deliberate. Chrome has been quietly installing an undeletable 4GB Gemini Nano model on its users' PCs. Meanwhile, browsers like Dia, Opera Neon, and Comet have been racing to build AI-first experiences that automate browsing and chat with tabs. Firefox's answer isn't to fold—it's to give users a choice.
Market position and the "no bloat" trend
Firefox holds approximately 4.44% of global browser market share, a far cry from Chrome's roughly 66%. That gap has been widening for years. But the browser space is shifting. In April, Brave launched Brave Origin—a paid browser build ($60 one-time, free on Linux) that strips out Leo, Rewards, Wallet, VPN, Tor windows, and telemetry. Before that, tutorials on manually "debloating" Brave had been going viral for years.
The fact that "no AI, no bloat" is now a paid product category says something about user frustration.
Mozilla's bet
Mozilla stated that Firefox is the only browser built for people, not platforms. Project Nova is the visual argument for that claim. Instead of fighting the AI wave, Firefox is letting users opt out entirely—a stance that mirrors its historical stance on privacy and user agency.
