This Chrome extension prevents opening of duplicate tabs so that you don’t have to hunt for them later. There are three prevention modes:

  • Keep New Duplicates: Close old duplicate tab and replace them with the newly opened one.
  • Keep Old Duplicates: Closes new duplicate tab and keeps the already opened tab.
  • Disable: Disables detection so that you can open duplicate tabs.

You can quickly switch between modes with one click on the extension icon in the toolbar.
