Hi everyone,
We’re starting an early test of Smart Window in Firefox and wanted to create a place to gather feedback.
If you’re here from Firefox and already have access to Smart Window, please tell us what’s working, what isn’t, and what you’d want next. If you’re visiting this post and don’t see Smart Window in Firefox yet, that’s expected: we’re starting by inviting a small number of waitlist users. You can sign up for the waitlist here: https://www.firefox.com/en-US/smart-window/?view=waitlist
First, and most important: the Firefox you already know isn’t changing. Your regular and private browsing windows work exactly as they do today.
Smart Window is a separate, optional window in Firefox where you can interact with an AI assistant of your choice while you browse, intended to think with you, not for you. It’s designed to help you:
A few things we want to be clear about:
This is still early, and we know AI in browsers raises real questions around trust, usefulness, and control. We’re trying to build this in a way that’s transparent and genuinely helpful in day-to-day browsing, but this is very much a work in progress.
Because this post is public, not everyone reading it will have access yet. That’s okay. General thoughts are welcome, and hands-on feedback from people using Smart Window in Firefox right now will be especially helpful as we improve it.
Thanks for helping shape where this goes.

The functionality required to make this work as anything other than the sidebar we already had is something that should be exposed to addon APIs.
And then we take this mess out of Firefox and put it into an extension.
