[Why is this notable]: First user-facing enablement of Auto Tab Grouping in
Smart Window. With one click, Smart Window now suggests organizing your open
tabs into named groups of related tabs, clustered and labeled entirely
on-device.

[Affects Firefox for Android]: No — Smart Window (and Auto Tab Grouping) is
Desktop-only.

[Suggested wording]: In Smart Window, Firefox can now organize your open tabs
into groups for you — suggesting groupings of related tabs and naming each
one, all on-device.

[Links (documentation, blog post, etc)]: N/A (internal tracking: AIAUG-201).

[Links (documentation, blog post, etc)]: https://www.firefox.com/smart-window is needed to activate the feature and it's region restricted, so we should probably show the "progressive roll out" indicator
