Giving this a first quick look: We’ll need to add the smartbar to ActionsProviderTabGroups plus potential adjustments in ActionsProviderTabGroups.sys.mjs as well as making sure CSS is applied correctly.

This will require some UX work.

I’m not sure there’s much UX work needed here. We should display tab groups the same way we do in the address bar dropdown. That said, if any questions come up or you'd like to discuss the UX, just let me know!

This can work like in the urlbar if we want to match.

I think the UX input tab group is was needed for bug 2014499: This bug around the @mentions popover and not the address bar suggestion list. So how tab groups are surfaced and shown here (as well as when inserted in the smartbar). At the moment only single tabs are supported.
