Firefox Smart Window: What It Is, How It Works, and Why It Matters

What is Firefox Smart Window?
Firefox Smart Window is an optional AI-powered browsing experience built into Firefox. It is designed to help users research, organize, and understand information without leaving their browser. Instead of opening a separate AI chatbot and manually providing information, Smart Window can work with browsing context that the user chooses to share, such as webpages, selected tabs, and browsing history.
When Was Firefox Smart Window Released?
Firefox Smart Window has been progressively rolled out during 2026 rather than being released everywhere on a single launch date. Mozilla has introduced the feature through multiple Firefox updates, gradually adding new AI-powered capabilities.
- Early 2026: Mozilla continued developing and testing its AI-powered browser experience.
- June 30, 2026: Firefox introduced Smart Window improvements including AI-powered tab actions and visual browsing-history results.
- July 14, 2026: Firefox added AI actions for selected webpage text, including summarization and explanation.
- August 4, 2026: Firefox added the ability for Smart Window to use web-search results from Exa.
- August 17, 2026: Exa announced that its AI search technology was powering Smart Window on Firefox desktop.
- August 18, 2026: Firefox added AI-suggested tab groups and suggested names for those groups.
- Current Status: Smart Window remains an optional, progressively rolled-out beta experience, so availability can vary between users.
How Does Firefox Smart Window Work?
Smart Window combines an AI assistant with the Firefox browsing experience. It can use the browsing context that the user chooses to provide and can also retrieve current information from the web through Exa.
- Browser Context: Smart Window can work with selected tabs, webpages, and browsing history to help users continue their research.
- AI Models: Firefox's approach allows users to choose from supported AI models instead of depending on only one model.
- Web Search: Smart Window can use Exa to search the live web, retrieve relevant information, and provide answers with sources.
- AI Processing: The retrieved information and selected browsing context can be used by the AI model to generate a useful response.
- User Control: Smart Window is designed as an opt-in experience, giving users control over the information and context they want to share with the AI.
How to Use Firefox Smart Window
- Step 1 - Update Firefox: Make sure you are using a supported, up-to-date version of Firefox on desktop.
- Step 2 - Open Smart Window: Launch the Smart Window experience from Firefox.
- Step 3 - Choose Your Context: Select the browsing information you want the AI to use, such as relevant tabs or webpages.
- Step 4 - Ask a Question: Ask Smart Window to summarize, compare, explain, research, or find information.
- Step 5 - Review the Answer: For web-based questions, Smart Window can use current information retrieved through Exa and provide relevant sources.
What Can You Do With Smart Window?
- Summarize Webpages: Quickly understand the key points of long articles and webpages.
- Research: Compare information from multiple webpages while researching a topic.
- Organize Tabs: Identify related tabs and suggest groups and names for those groups.
- Find Browsing History: Use natural-language descriptions to help locate pages you previously visited.
- Explain Content: Select text on a webpage and ask the AI to explain or summarize it.
- Search the Current Web: Ask questions that require up-to-date information and use web results retrieved through Exa.
Why Should You Use Firefox Smart Window?
The main advantage of Smart Window is that it connects AI with the browsing workflow. Instead of leaving the browser, opening a separate AI application, and manually copying information, users can get AI assistance while working with their existing web research.
- Less Manual Work: You do not always need to copy and paste information from multiple webpages into an AI chatbot.
- Better Research: Smart Window can help compare and summarize information from your browsing context.
- Better Tab Management: It can help organize large numbers of open tabs into meaningful groups.
- Current Information: Exa-powered web search allows Smart Window to retrieve information from the current web.
- Browser-Native Experience: The AI assistant is designed around the browser rather than being a completely separate application.
- User Control: Mozilla emphasizes that Smart Window is optional and gives users control over what browsing context they share.
Firefox Smart Window vs ChatGPT
Firefox Smart Window and ChatGPT are not exactly the same type of product. ChatGPT is a general-purpose AI assistant that can help with coding, writing, reasoning, learning, analysis, and many other tasks. Smart Window is specifically designed around the web browsing experience.
- ChatGPT: A general-purpose AI assistant for reasoning, coding, writing, learning, research, and many other tasks.
- Smart Window: An AI browsing assistant designed to work with webpages, tabs, browsing history, and web research.
- ChatGPT's Strength: General AI assistance across many different types of tasks.
- Smart Window's Strength: Connecting AI directly with the user's browser workflow and browsing context.
How Is Smart Window Different From a Traditional Search Engine?
A traditional search engine primarily helps you find webpages. Smart Window goes a step further by combining web search with AI and browser context. Instead of simply returning a list of links, it can help interpret, summarize, compare, and organize the information you are working with.
- Traditional Search: Find webpages related to your query.
- AI Search: Find information and generate an answer.
- Smart Window: Combine AI assistance, live web search, and your selected browsing context.
Privacy and User Control
Privacy is an important part of Mozilla's approach to Smart Window. Mozilla describes the feature as optional and emphasizes giving users control over what information the AI can access. Mozilla also says Smart Window memories are stored locally on the device and can be deleted by the user.
The Role of Exa
Exa provides the web-search technology used by Smart Window for retrieving current information from the internet. When a question requires fresh web information, Exa can search, retrieve, and rank relevant content that can then be used by the AI to generate an answer with sources.
- Firefox: Provides the browser and browsing context.
- Smart Window: Provides the AI-powered browsing experience.
- Exa: Provides AI-focused web search and retrieval.
- AI Model: Processes the available information and generates the response.
Conclusion
Firefox Smart Window represents a different approach to browser-based AI. Instead of being only another chatbot, it connects AI with the user's existing browsing workflow. Its ability to work with selected browsing context, organize tabs, search browsing history, summarize webpages, and retrieve current web information through Exa makes it particularly useful for people who spend a lot of time researching online. While ChatGPT remains a broader general-purpose AI assistant, Smart Window focuses specifically on making the browser itself more intelligent.
