While Google spent the entire week at its I/O developer conference showing off new artificial intelligence features, Mozilla decided to take a different approach with its latest browser update. On Tuesday, the company released Firefox 151, which brings a new set of AI controls to mobile devices. Users on iOS and Android can now finally decide if they want their browser to use generative AI features or if they prefer to keep things traditional.
Mozilla added a simple binary toggle that acts as a master switch. If you don’t like artificial intelligence in your browser, you can flip one button to turn off every single generative AI feature at once. For those who enjoy some parts of AI but dislike others, the update also offers a granular menu. You can pick and choose exactly which tools stay active and which ones get disabled, giving you full control over your digital experience.
The browser does include several useful AI tools, such as voice search and automatic page translations. Mozilla argues that these features help people save time, but they clearly understand that not everyone wants their browser to “think” for them. By offering this total opt-out capability, Mozilla is doing something very rare in the tech industry. Most companies now bake AI into their products so deeply that you cannot escape it even if you try.
This move stands in sharp contrast to companies like Google, which currently pours over $1 billion into AI development and expects every user to adopt the tech. When Mozilla launched these same controls for its desktop browser back in February, users cheered the move. It proved that at least one major browser maker cares more about user preference than it does about forcing the newest tech trends onto the public.
Mozilla also continues to play a major role in the broader debate about how we should build and secure AI. The nonprofit recently caught the attention of the tech world for its involvement in Anthropic’s Project Glasswing. During that project, Mozilla shared compelling data about the role AI plays in cybersecurity. They proved that AI can act as both a massive threat—by finding hidden security holes—and a powerful shield—by helping developers patch those holes before bad actors exploit them.
The cybersecurity research from Mozilla serves as a reminder that AI is not just a toy for generating funny images or writing emails. It is a powerful engine that can either break or build our digital defenses. By giving users the choice to turn off AI, Mozilla is acknowledging that the technology still has a long way to go before it is perfect. If you don’t feel comfortable with an AI “agent” browsing the web on your behalf, you now have a legal and technical way to opt out.
Mozilla currently faces a tough challenge. They operate as a nonprofit, meaning they don’t have the $1 billion-plus war chests that companies like Google or Microsoft use to fund their AI experiments. Yet, by focusing on user choice and privacy, they have carved out a loyal following. Many people who feel overwhelmed by the current “AI gold rush” are switching to Firefox simply because it feels like a browser that listens to its users.
This update also marks an interesting turning point for the mobile web. For years, mobile browsers were quite limited in what they could do. With the arrival of Firefox 151, mobile users finally get the same level of control that desktop users have enjoyed for months. It shows that Mozilla wants to treat the phone browser as a serious tool for power users rather than just a way to view simple web pages.
If you are currently using the Firefox app on your phone, you should look for the update in the app store immediately. After you download version 151, you can head into the settings menu to see the new AI controls for yourself. It is a breath of fresh air to see a company admit that users might actually prefer a simpler, AI-free experience. Whether you want to use the newest translation features or keep your browser strictly focused on manual navigation, Mozilla has finally given you the keys to your own house.
