Exemples

Cette extension écoute onChanged, puis restaure  immédiatement la dernière session fermée, ce qui rend impossible de fermer les fenêtres ou les onglets :

function restoreSession(sessionInfos) {
  if (!sessionInfos.length) {
    console.log("No sessions found")
    return;
  }
  let sessionInfo = sessionInfos[0];
  if (sessionInfo.tab) {
    browser.sessions.restore(sessionInfo.tab.sessionId);
  } else {
    browser.sessions.restore(sessionInfo.window.sessionId);
  }
}

function onError(error) {
  console.log(error);
}

function restoreMostRecent() {
  var gettingSessions = browser.sessions.getRecentlyClosed({
    maxResults: 1
  });
  gettingSessions.then(restoreSession, onError);
}

browser.sessions.onChanged.addListener(restoreMostRecent);
