States push back against rising AI-driven electricity infrastructure costs | Daily Reports Online
As AI becomes a greater and more important presence in our everyday lives, the way we interact with the “traditional” internet is changing.
For so long the main way to access the internet, the web browser is now having to rethink how to appeal to an audience which often seeks AI-first interaction – raising new challenges for developers to create the best and most interactive experience.
We spoke to Ajit Varma, Head of Firefox at Mozilla, to find out more.

- The web has always been built on the principles of openness and interoperability, but today’s internet is increasingly shaped by a handful of dominant platforms and AI-powered services. What does the ‘open web’ mean in 2026, and why does it still matter?
The open web matters more today than it has in years because AI is changing how people experience the internet. As a small number of platforms become the gateway to search, content and AI-powered services, it’s becoming easier for a handful of companies to shape what people see and how they interact online.
That’s why the principles of the open web still matter. Common standards mean developers can build without asking permission from a dominant platform, and users can choose how they access the web rather than being locked into a single ecosystem. Those principles have driven innovation for decades, and they’re just as important as AI reshapes the internet.
The challenge now isn’t simply keeping the web open as it exists today. It’s making sure openness evolves alongside AI, so the next generation of the internet remains competitive, interoperable and accessible to everyone
- AI is changing the way people discover information and interact with the internet. How do you see browsers evolving over the next five years, and what role should they play in helping users navigate an increasingly AI-driven web while maintaining trust and choice?
Over the next five years, you’ll start to see more divergences in how browsers treat AI. Many companies will use the browser to try and push a specific AI agenda but at Firefox we’re focused on how AI can make the tasks a user wants to do in a browser better. This includes things like a personal agent that can help a user accomplish tasks, navigating the web through voice, making the web more enjoyable, and creating new vibe-coded extensions and mini-apps.
We’ll do all this in a way that is user centric. The browser should adapt to the user, rather than the other way round. Some people will want AI integrated into their everyday browsing, while others will prefer to use it for specific tasks. Maintaining trust means supporting those preferences and letting people decide how much they use AI.
Users should be able to choose any model they want including open and local models. The important thing is preserving that flexibility, so people can browse, search and get things done in a way that feels natural to them.
- Privacy has long been a core part of Mozilla’s mission, but consumers also expect convenience and highly personalised online experiences. How do you strike the right balance between protecting users’ privacy and delivering the features people now expect from modern web experiences?
For me, striking the right balance starts with recognising that every user has different expectations of their browser. While context can make online experiences more useful and personalised, people should be able to understand how their data is used and decide what they are comfortable sharing. By giving users meaningful control over the features they adopt, Firefox can deliver modern experiences while continuing to protect their privacy.
This has guided our phased approach to AI, beginning with practical features such as summarisation, translation, tab organisation and optional AI chat integrations. Before introducing more advanced AI experiences such as Smart Window, we launched AI Controls so people can manage individual features or switch them off altogether.
Firefox is also model-agnostic, so users can choose or switch providers, use local models, or opt out entirely. Even though only a small minority of users disable AI features, people regularly tell us they value knowing the controls are there. Privacy and convenience can coexist when people are able to set the terms of the experience.
- There’s growing concern that the future of the web could become fragmented between closed AI ecosystems, proprietary platforms and app-based experiences. What do you see as the biggest threats to the open web, and what gives you confidence that it can continue to thrive?
The biggest risk isn’t AI itself, it’s concentration. If the same companies control the AI models, the interface people use to access them and the browser they interact through, users lose visibility, choice and ultimately agency. That’s a much bigger shift than simply moving from one technology generation to another.
What’s encouraging is that the issue is becoming harder to ignore. Developers want open standards. Regulators are paying closer attention to competition. Users are asking tougher questions about transparency and control. The web has always evolved through periods of disruption, but it has remained resilient because it’s built on interoperability rather than permission. AI can strengthen that model rather than replacing it with a handful of closed ecosystems. The future doesn’t have to be a choice between innovation and openness. We should expect both.
- Developers have always been central to Mozilla’s community. As AI transforms software development and web creation, how do you think the relationship between developers, browsers and the open web will change over the coming years?
AI is making it dramatically easier to build software, which means we’re going to see more developers – and more people who aren’t traditional developers – creating for the web. That’s a huge opportunity, but only if they can build on an open platform rather than for a handful of closed ecosystems.
That’s why the browser becomes even more important. It’s no longer just where websites are displayed – it’s becoming the layer where people interact with AI to search, create, organise information and complete tasks. As that layer becomes more powerful, it has to remain open, interoperable and centred around user choice.
For developers, that means being able to build for the web, rather than for whichever company happens to control the dominant model or platform. That’s always been one of the web’s greatest strengths, and it’s something we shouldn’t lose as AI reshapes how software is built and experienced.
- If you look ahead to the end of this decade, what do you hope people will say about the state of the web? What would success look like for Mozilla’s vision of an open, healthy internet?
Success, for me, is a web that’s become more useful through AI without becoming less open. Technology should expand what’s possible, not narrow the ways people can access information, build new ideas or participate online.
Innovation should continue to come from everywhere, not just a handful of dominant platforms. The web has always been at its best when anyone with a good idea can build something that reaches millions of people. That only happens when developers have open standards to build on and users aren’t locked into a single ecosystem.
The web should still be the best place to build, discover and innovate because it remains accessible to everyone. If AI has expanded participation rather than concentrated power, we’ll be heading in the right direction.
- Mozilla is competing in a browser market dominated by much larger technology companies. How do you differentiate Firefox, and why do you believe there’s still a commercial and societal case for an independent browser?
We differentiate through independence, choice and accountability. Most browsers are tied to larger technology ecosystems spanning across multiple systems, search, advertising and AI.
Instead, Firefox is powered by Gecko, the only remaining independent browser engine, which gives us the freedom to make product decisions around what benefits users. It ensures that Mozilla is not only advocating for these principles but actively building the underlying infrastructure that makes them possible.
That independence is commercially relevant because there’s such a clear demand for genuine choice. Firefox has been selected through EU browser choice screens more than six million times in two years and those users are five times more likely to remain with Firefox than people who find it organically.
Societally, independent engines prevent one company’s technical and commercial priorities from being the default for the entire web. They also preserve competition, interoperability and the ability to build around different values.
- As regulators around the world seek to promote competition in digital markets, are we at a turning point for the open web, or is there still a risk that power becomes even more concentrated through AI?
There are certainly some encouraging signs that regulation can restore meaningful choice. The impact of browser choice screens in Europe shows that people choose alternatives when they are presented fairly and without being steered towards a default.
However, AI is creating a new concentration risk. If the same small group of companies control the operating system, browser, search engine and AI model, it becomes much easier for them to shape how people access information and which services they encounter.
Regulation needs to keep pace not only with how AI is developed, but with how it’s distributed and embedded into everyday products. However, regulation can’t do this alone. Interoperability, genuine defaults and strong technical competition will matter just as much.
- Trust has become a key differentiator in technology. How can browser makers earn and maintain users’ trust as AI assistants become embedded in everyday web browsing?
Trust starts with being clear about what the technology is doing. AI should be optional, transparent and designed so users can understand what information it can access, how it’s being used and who is acting on their behalf.
That’s the principle behind Firefox’s AI controls. AI features are optional and can be managed individually, while a single setting allows users to block current and future generative AI features. We also use on-device models for features such as Link Previews and Smart Tab Groups, allowing people to receive AI assistance without any data leaving their device.
Ultimately, trust isn’t earned through a single feature. It’s earned by being transparent about how AI works and consistently respecting the decisions people make.
