About this extension
Features
  • Set a different home URL per container (plus one for "No container / Default").
    Click the toolbar button, or press Alt+Shift+Home, to load that
    container's home URL in the current tab.
  • Set up to 9 app slot URLs per container. Press Alt+Shift+1 through
    Alt+Shift+9 to switch to that slot's tab — scoped to whichever
    container is currently active — or open it in a new tab if it isn't
    already open. If the tab lives in another window, that window is raised
    too.
  • Slots remember the exact tab they last switched to (not just a URL
    pattern), so navigating around inside an app (e.g. different Slack
    channels or Gmail threads) doesn't break the binding. If that tab is
    closed or the browser restarts, the next press falls back to matching by
    the slot URL's origin, or opens a fresh tab if nothing matches.
  • Export your configured home URLs and slots to a JSON file, and import them
    back in (on this device or another). Importing replaces the current
    configuration after a confirmation prompt.

Permissions
  • activeTab — read the current tab's container and navigate it to
    the configured URL.
  • tabs — find a slot's existing tab (by remembered id, or by URL as a
    fallback) across all of a container's tabs, and re-focus its window.
  • cookies — required by Firefox to open a new tab in a specific container
    (tabs.create with cookieStoreId) when a slot's tab isn't already open.
  • contextualIdentities — list your Firefox containers on the options page.
  • storage — save your configured URLs locally, and remember which tab
    each slot last switched to for the current browser session.
