Firefox’s Smart Window gets live web links, history previews and more AI controls

Updated August 18, 2026 4:53 pm

Mozilla has updated Firefox’s Smart Window beta with live web-backed answers, source links, smarter history search and tab-group suggestions, sharpening its pitch as a privacy-minded AI browser. The changes matter because Mozilla is trying to add useful AI features without turning Firefox into a tool that constantly pushes users toward chatbots or data-heavy automation.

The new capabilities, announced on Tuesday, deepen Firefox’s attempt to make AI feel like a helper inside the browser rather than a replacement for it. Smart Window can now pull current information from the web through a partnership with Exa, cite those sources in responses, and help people rediscover content they viewed days earlier using plain-language prompts such as “running shoes I looked at last week.”

That places Firefox in a crowded race among browsers adding generative AI, but Mozilla is taking a different path: opt-in by default, model choice for users, and stricter limits on what the company says it stores. The latest update also underscores a wider strategy inside Firefox: use AI where it improves the browsing workflow, then keep the rest of the browser familiar and under user control.

What Mozilla changed in Smart Window

The biggest addition is real-time web grounding. Smart Window can now answer with information drawn from the current web and attach source links directly in the chat interface. Mozilla says the feature is designed to make answers easier to verify and more useful when the user is looking for something recent or fast-changing.

Instead of treating AI as a separate destination, the browser now tries to weave it into the places where people already spend time: search history, open tabs and previously visited pages. The company also says Smart Window can suggest tab groups automatically and surface visual previews from earlier browsing sessions when users search their history in natural language.

In practical terms, that means someone who vaguely remembers looking at a product page, a recipe, a travel article or a research result should be able to ask Firefox to find it again without having to remember the exact site or tab name.

How does the new web search feature work?

It works by letting Smart Window fetch up-to-date web information and present it with citations, rather than relying only on the model’s internal knowledge. Mozilla says the Exa integration helps the browser retrieve current results and show where the information came from.

That matters because general-purpose AI chat often struggles with recency. By pairing the chat interface with source-backed retrieval, Firefox is aiming to reduce hallucinations and make the feature more useful for checking facts or verifying a response.

Mozilla says the new system is intended to help users confirm answers and recover their place in a browsing session, especially when they remember the content of a page but not the page itself.

Why Mozilla thinks AI should help browsing, not replace it

Mozilla’s argument is straightforward: browsers should remain browsers. In contrast with products that center the user experience around chatbot interactions, Firefox is positioning Smart Window as one feature among many, not the main reason to open the app.

Ajit Varma, who leads Firefox at Mozilla, said the company is pursuing what he described as an agnostic approach to AI. In other words, Firefox will support AI tools for people who want them, but it does not want those tools to dominate the browser or become mandatory.

The philosophy reflects a long-running Mozilla theme. The company has repeatedly tried to differentiate Firefox from larger rivals by leaning on user choice, open web principles and a more restrained view of product bundling. With AI, that means giving users a path to experiment without forcing a single vendor, model or workflow on everyone.

What Mozilla means by a user-first AI browser

Mozilla says user-first means features should solve concrete browsing problems: getting back to a page, grouping tabs, comparing sources or filling out forms faster. It does not mean turning the browser into a chatbot tab with a URL bar attached.

That distinction is central to the company’s messaging. Mozilla argues that the browser should remain a neutral tool on the open internet, even as it adds generative features. It wants the AI layer to feel optional, not extractive.

Users can choose their own AI model

Another notable part of the update is model choice. Firefox users can select from a range of AI models in Smart Window, including Google Gemini 3.1 Flash Lite, OpenAI’s oss-gpt-120b, Alibaba’s Qwen3-235B-A22B-Instruct-2507, or local models running on their own machines.

That flexibility is unusual in consumer browsers and aligns with Mozilla’s broader pitch around digital sovereignty. The company says people should be able to choose models based on privacy preferences, regional availability or philosophical preference rather than having to accept a single default.

The option to use local models is especially important for users who want more control over where their data goes. It also reduces reliance on a single cloud provider and gives Firefox a more open, modular feel than competing AI browser products that bundle their own assistants tightly into the interface.

What is digital sovereignty in this context?

In Mozilla’s framing, digital sovereignty means giving people and organizations more control over which AI systems process their data and where that processing happens. A user in one region may want a local provider, while another may prefer a model from a company with stricter privacy terms or different policy priorities.

It is also a response to a broader concern in AI: a handful of large vendors increasingly control the infrastructure behind everyday tools. By supporting multiple models, Firefox is trying to resist that lock-in.

How Mozilla says Smart Window handles privacy

Mozilla is making privacy a central selling point for Smart Window. According to Steve Truong, a senior product manager on Firefox AI, the third-party models available in the feature operate under zero-data-retention agreements.

That means user prompts are processed in memory and are not supposed to be stored for model training, advertising, broader analysis or human review. Mozilla also says it does not keep user chats on its own servers unless the user explicitly allows it for specific purposes such as model training.

The company’s promise is not simply that it avoids one kind of misuse. It is trying to draw a line between helpful AI features and the much more controversial data practices that have fueled skepticism toward consumer AI products.

Truong said Mozilla’s partners are expected to process prompts without retaining them for training, ads or human review, and added that Firefox itself does not store chats unless a user opts in for a specific reason.

That language is designed to reassure users who may want AI in their browser but not at the cost of a permanent data trail. It is also an attempt to differentiate Firefox from systems that treat user interactions as future training material by default.

What users can do now in Smart Window

Mozilla’s demo showed Smart Window doing more than answering questions. It could sift through selected links in browsing history, retrieve a page about “running shoes I looked at last week,” and show images pulled from sites previously visited. It also demonstrated tab management features that identify related pages and close duplicates.

Those are small but practical use cases. They focus less on novelty and more on workflow: finding things faster, keeping tabs under control and using AI to sort through digital clutter that many browser users already deal with every day.

Mozilla says beta users have told the company that the feature helps them maintain their train of thought. That is an important claim because one of the quiet frustrations of modern browsing is cognitive friction: people jump between tabs, lose track of sources and struggle to reconstruct what they were doing.

Future features Mozilla says are coming

Mozilla says the next wave of updates will include a browser-history feature similar to the way Chrome surfaces recent browsing journeys, as well as AI-powered autofill for online forms. Both features would extend Smart Window further into everyday browser tasks while keeping the experience tied to normal browsing behavior.

That roadmap suggests Mozilla is not treating the current update as a finish line. Instead, the company seems to be building a broader AI layer that helps users navigate memory, context and repetitive inputs without becoming a full assistant platform.

How Smart Window compares with other AI browsers

Firefox’s approach differs from browsers that use AI to make the browser itself feel like a destination. Mozilla’s leaders have been explicit that they do not want Firefox to become a product whose main purpose is to generate more chatbot queries.

That contrast is one reason Smart Window is notable. Many AI browser efforts emphasize task completion, page summarization or automated actions. Firefox is emphasizing optionality, history recovery and source-backed browsing support.

That does not mean Mozilla is avoiding the AI trend. It means the company is trying to fold it into a browser-first experience rather than redesign the entire product around an assistant.

Comparison at a glance

• Firefox: optional AI features, model choice, privacy messaging and browsing workflow integration.
• AI-first browsers: chatbot-centered interfaces, stronger reliance on a single model or vendor stack.
• Key difference: Firefox is trying to be a browser that includes AI, not an AI product that happens to browse.

What the beta status tells us

Smart Window remains an opt-in beta, and Mozilla has not given a firm date for when it will graduate from testing. Varma said there is no exact timeline yet, which suggests the company is still gathering feedback and refining the feature set.

The staged rollout is consistent with Mozilla’s user-feedback-driven approach. The company says it has already made changes based on what testers asked for, including adding a top navigation bar to Smart Window.

That matters because browsers are highly habitual products. Users do not tend to tolerate sudden UI overhauls or intrusive experimental features. By keeping Smart Window optional and iterating in public, Mozilla reduces the risk of alienating the very audience it hopes will adopt the feature.

Timeline: how Firefox’s AI browser mode evolved

Smart Window did not appear overnight. It is the latest step in a broader rollout that has been evolving for more than a year.

Why this update matters for Firefox

The update is important because Firefox has long faced pressure to distinguish itself in a market dominated by browsers from companies with far larger ecosystems. AI is one of the few areas where a smaller player can still make a meaningful product argument: better control, better privacy and a less invasive experience.

Mozilla is betting that some users want AI help but do not want their browser to feel like a funnel into a single company’s cloud. Smart Window is designed to capture that audience by making AI useful without making it the center of gravity.

If it works, Firefox could carve out a distinctive position among AI browsers: one that combines retrieval, citations, local model support and stricter data handling with ordinary browsing features like tabs and history. If it does not, the feature may remain a niche experiment for power users.

What to watch next

The most important question is whether users actually adopt Smart Window beyond curiosity. Browser AI features often sound impressive in demos but struggle to become part of routine behavior unless they solve everyday annoyances with very little friction.

For Mozilla, the next phase will likely depend on three things:

1. Whether users trust the privacy story.
2. Whether model choice is simple enough to matter.
3. Whether history recovery and tab organization save enough time to become habit-forming.

Mozilla’s leadership appears to understand the stakes. Rather than pitching Smart Window as a revolutionary new interface, the company is framing it as a practical tool that quietly improves Firefox for people who want AI support and leaves everyone else alone.

That may be the most telling detail of all. In a market where many AI products aim to expand the role of the chatbot, Mozilla is trying to preserve the browser as the primary interface to the web — just one that can now help you remember where you were, what you saw and which page you meant to return to.
