Firefox Smart Window Adds AI Form Filling and Webpage Monitoring in Beta

Mozilla has enhanced Firefox's AI-powered Smart Window with two new features, "Smart Form Fill" and a "/watch" task, now live in beta for desktop users in the US and Canada. These updates enable the browsing sidebar to complete online forms using context from open tabs and monitor webpages for changes, transforming the browser into a more interactive tool.

Enhanced Form Completion with Smart Form Fill

The new Smart Form Fill feature is designed to automatically complete online forms by drawing context from other open tabs in Firefox. This functionality activates on forms containing at least four text fields, allowing users to select which open tabs Firefox can reference for information. Mozilla has confirmed that data from source pages is shared with Google's Gemini 3.1 Flash Lite model to generate these suggestions.

Currently, Smart Form Fill supports text fields. Mozilla has indicated that support for dropdown menus and PDF forms is under development, suggesting future expansions to its utility.

Automated Webpage Monitoring with '/watch' Tasks

Firefox's Smart Window now includes a "/watch" task feature, enabling users to monitor specific webpages for changes. This can be used to track updates such as price drops or new job listings. Users receive notifications daily or weekly, but only while the browser is open.

Monitoring for "/watch" tasks operates with specific limitations: it pauses after 60 days if no changes are detected on the page and stops entirely after 90 days without any activity. This mechanism ensures that monitoring resources are not indefinitely allocated to static pages.

Availability and Future Plans

These new features are live in the Smart Window beta for desktop users in the United States and Canada. Mozilla plans to roll out these capabilities to other countries "in the coming months." The company has also previously indicated that future updates will include options to manage AI features individually, allowing users to block specific generative AI functionalities.

Data Privacy and AI Integration

Mozilla explicitly states that data from source pages is shared with Google's Gemini 3.1 Flash Lite model to power the AI suggestions. This transparency addresses how user data is processed to facilitate the new AI-driven functionalities within Smart Window. Users interested in understanding more about AI tools and their data practices can explore resources on AI news and developments.

Conclusion

The introduction of Smart Form Fill and the "/watch" task feature marks a notable evolution for Firefox's Smart Window. By integrating AI capabilities for form automation and webpage monitoring, Mozilla aims to provide a more interactive and proactive browsing experience. As these features move beyond beta and expand to more regions, they could offer practical benefits for users seeking to streamline online tasks and stay informed about web content changes.
