When you’re filling out a form, Smart Window can recognize the context of the form, the type of information it’s asking for, and help you fill the form faster. It does this by finding suggestions in your related open tabs.

For example, if you’re completing a job application in one tab and have your profile or a resume open in another, Smart Window can find suggestions for how to fill the job application fields, a step that otherwise requires manual entry or copy and paste. Smart Window prompts you to review any suggestions it finds before filling them in, so you’re always in control.

Any autofill information you already have saved in Firefox (Settings > Passwords and autofill), such as your name, address, passwords, and payment information, gets filled as usual, directly from the data stored on your device. Nothing leaves your device or is sent to any AI model.

Fill out a form with Smart Window

1. Open a form in Smart Window, such as a job application.
2. Click or tap into an input field. If the form is supported and has at least five text fields Smart Window can help fill, the Fill from sources option appears.

   

   

3. Select Fill from sources.

   

4. Click on the suggested tabs to review which to use as sources.
5. Select or deselect tabs depending on which ones you want Smart Window to use.

   

6. Continue to get suggestions for how to fill fields.
7. Review the suggestions and make any necessary changes before filling the form.

   

Choose which tabs Smart Window can use

When suggesting tabs to use as sources, Smart Window looks for open tabs that are relevant to your form and may contain useful information related to the form you're filling. You're in control of which tabs Smart Window uses.

Before filling the form, you can:

• Review the suggested tabs.
• Deselect tabs you don't want to use.
• Select other relevant tabs you have open.

Smart Form Fill uses the selected sources to help generate information for fields that regular Firefox autofill can't complete.

How Smart Window works with saved autofill information

Information you already saved locally in Firefox for autofill (Settings > Passwords and autofill), such as your name, address, password, or payment information, can be inserted directly into supported fields as usual. Nothing leaves your device or is sent to any AI model.

For other fields, Smart Window attempts to understand the context of the form and use information from the sources you select to suggest what data to use or a response to enter.

Frequently asked questions

Why don't I see the Fill from sources option on every form?

The Fill from sources option only appears on supported forms that have at least five text fields Smart Window can help fill.

Online forms are built differently, so Smart Window may not recognize every form or field type. If you don't see the option, the form may not be supported or may not have enough supported fields.

You can still fill out the form manually or use Firefox's regular autofill features where available.
