For Chrome (related post), there is a Tab Dupectomy extension.

I am looking for something similar, but for Firefox Quantum.

I have checked few such as Duplicate Tab or Duplicate This Tab, but these add-ons aren't compatible with Firefox Quantum.

    Tab Dupectomy is LGPL-licensed and the code is available on GitHub -- if you wanted, you could probably port it to Firefox pretty easily.

I can recommend ClickTabUniq,

With this Firefox extension, you can close duplicate tabs from the context (right-click) menu on tabs or directly on the page (configurable).

It is fully compatible with Firefox Quantum.
