Tab actions

Every tab card in the list has three buttons, left to right:

  1. Attach via CDP (plug icon) - brings that tab to the front in the remote instance, then opens CDP Inspector’s own inspector panel (attach.html) in a new tab of your local browser, pre-wired to that target’s CDP WebSocket. This is the extension’s custom UI - see The inspector panel.
  2. Open DevTools (external-link icon) - opens the real, full Chrome DevTools frontend (served by the remote instance itself at /devtools/inspector.html) against that tab, in a normal new tab of your local browser. Use this when you want the actual DevTools Elements/Sources/Performance panels rather than CDP Inspector’s own UI.
  3. Close tab (red X) - closes that tab in the remote instance and refreshes the list. The button disables itself while the request is in flight.

Both “Attach via CDP” and “Open DevTools” open in your own, local browser - not inside the remote throwaway instance.
