sessions.forgetClosedWindow() 编辑

Removes a closed window from the browser's list of recently closed windows. Note that the sites visited by that window are not removed from the browser's history. Use the browsingData or history APIs to remove history.

This is an asynchronous function that returns a Promise.

Syntax

var forgettingWindow = browser.sessions.forgetClosedWindow(
  sessionId            // string
)

Parameters

sessionId

String. The ID of the session you want to forget.

Return value

A Promise. This will be fulfilled with no arguments when the session has been removed.

If an error occurs, the promise will be rejected with an error message.

Examples

This code forgets the single most recently-closed session, whether it's a tab or a window:

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

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

browser.sessions.getRecentlyClosed({maxResults: 1})
.then(forgetMostRecent, onError);
