Tab Origin

Adds button/shortcut to return to the page from which you opened the current tab.

Never forget where your tab came from again! Have you ever spammed undo-close-tab multiple times to figure out what you accidentally closed a while back? Not again, activate this extension to jump straight there!

If origin page is already open, then we switch to that tab. Otherwise we open it in a new tab.

You can even use it recursively on tabs opened by tab origin; the extension tracks the history.

I suggest the shortcut is cmd/ctrl-shift-u, set from the bottom of Extensions page. When origin information is unavailable for a tab a "N/A" badge is shown.
