Firefox's New AI Mode Fills In Your Forms Automatically

Mozilla has launched Smart Window, a new AI-powered browsing mode built into Firefox. It automatically fills in web forms using details you have already saved, and it can watch a page and tell you when something on it changes, rather than you checking back manually.

For a UK trades or construction business, this lands on the dullest part of the job: the forms. Supplier reorder portals, council licensing applications, plant hire sites, insurance renewal pages. Each one wants the same handful of facts: company number, VAT number, insurance certificate details, site address, contact name. You type them in fresh every time because the sites do not talk to each other.

Worked example. Say your office types out business details into ten separate web forms a week, taking roughly five minutes each because you are copying details from a folder or a previous email. That is fifty minutes a week. Across a working year that is close to forty hours, a full working week, spent re-entering information the business already holds. Smart Window is built to remove that specific task, not the thinking around it, just the typing.

The page monitoring side matters too. If someone in your office currently checks a supplier's price page, a council planning portal, or a tender site once a day just in case something has changed, that habit is quietly eating minutes across the week. Letting the browser watch the page and flag a change means that person only looks when there is actually something to look at.

None of this replaces judgement. A form with financial or legal consequences, a VAT return, a contract variation, an insurance declaration, still needs a human to check the output before it is submitted. The saving is in the retyping, not the responsibility.

What to do this month:

• Update Firefox and turn on Smart Window.
• Pick one form your business fills in repeatedly, a supplier reorder or hire request is a good test.
• Run it through Smart Window once and check every field against the original by hand.
• Only trust it on forms with no financial or compliance risk until you have tested it over a few weeks.
• If it holds up, hand the task to whoever currently does that typing and give them the time back.
