sessions.forgetClosedTab() - Mozilla | MDN
Toggle sidebar
sessions.forgetClosedTab()
Removes a closed tab from the browser's list of recently closed tabs. Note that the sites visited by that tab 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
js
let forgettingTab = browser.sessions.forgetClosedTab(
windowId, // integer
sessionId // string
)
Parameters
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:
js
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);
