Mozilla Tests AI ‘Smart Window’ in Firefox—Opt-In Only

The opt-in framing is the notable part: Mozilla is treating an assistant beside the tabs as a privacy question first, not a productivity one, which sets it apart from assistants bundled as defaults elsewhere. The choice of assistant matters less than the toggle, since a feature users must actively enable changes the adoption math and the data-collection debate around it. Whether that opt-in design holds as the test expands, and how the assistant selection is governed, is the open question.
