Mozilla has added AI-based online form filling and webpage change tracking to its Firefox web browser. The move aims to reduce the hassle of users entering information themselves or repeatedly checking websites.

According to U.S. tech outlet The Verge on Oct. 27, Mozilla introduced form-filling assistance and webpage monitoring features to the beta version of its AI-based browsing service Smart Window.

The form-filling assistant uses information from webpages the user has open. For example, it can pull work history from an online portfolio or LinkedIn and suggest what to enter on a job application form.

Users can use the feature by selecting "Fill from sources" on forms that have 4 or more text input fields. Users can choose or exclude tabs for the AI to reference, and can review and edit the generated text.

For now, it supports only text input fields in web forms. Support for dropdown menus and PDF forms is under development. It also does not automatically submit AI-written content.

Users also need to be careful about personal data handling. Information from source pages used for form filling is shared with Google's AI model Gemini 3.1 Flash Lite. By contrast, names and addresses saved in the existing autofill feature are processed on the device.

The newly added webpage monitoring feature notifies users when changes occur that match conditions they specify. It can be used to check for product price cuts or new job postings.

Users can type "/watch" in the Smart Window chat box and set the page to monitor and the conditions. The check interval can be set to daily or weekly, and up to 5 pages can be registered per task.

When a change is detected, it notifies users via the browser toolbar or desktop notifications. Up to 15 tasks can run at the same time, but checks are performed only when the browser is running. Monitoring is paused if there are no changes that match the conditions for 60 days, and the task ends if there are no changes for an extended period. Alibaba's AI model Qwen is used to detect page changes.

The two features are currently available in the English-language desktop Smart Window beta in the United States and Canada. Mozilla plans to expand support to other countries within the next few months.
