I'm on Android. As others have stated, it just closes the tab without reopening it as a private tab. It would be an awesome add-on if it worked

Edit: I changed my rating because of the reply

Don't work here. Just kill current tab and nothing in private.
Ok, thanks for reply. I put 4 star just to not cause a low rating.

The idea is nice and would do just what I wanted, but it does not work. Issues found:
- If a private window is open, it does not seem to work. Even after closing the private window that was open, it does not work.

- The original tab is closed, but the new private one is not opened, so it forces you to recover the closed tab.

Thanks
