The Add-profile menu buried imports in nested submenus and disabled rows —
a running browser was a dead "quit it" line you couldn't act on, and picking a
source profile meant hunting through submenus. The menu now lists each browser
as a plain row; clicking one opens a wizard that carries the whole import.

The wizard has a screen for every state instead of a disabled row: quit the
browser and retry, choose which source profile and where it lands, then import.
A new target profile is registered only once cookies actually arrive, so a
blocked or empty import leaves nothing behind.

Sources are cached and refreshed without blanking, so the menu no longer
reflows on open. The step transitions are pure and tested.
