I am looking for a new extension for Chrome/Chromium similar to Self-destructing cookies in Firefox.
In this Super User question, an answer was validated suggesting Tab Cookies. This extension seemed to fit the bill at the time (delete both cookies and local storage data whenever all tabs from one domain were closed). Unfortunately it seems to have stopped working. More precisely, I have checked the cookies with CCleaner after closing the browser, and they were still there, along with local storage.
As a temporary solution I have set up the browser to delete all cookies when closed, but it is not completely satisfactory.
