Restores a closed tab or window. Restoring doesn't just reopen the tab or window: it also restores the tab's navigation history so the back/forward buttons will work. Restoring a window will restore all the tabs that the window contained when it was closed.
This is an asynchronous function that returns a Promise.
Syntax
var restoringSession = browser.sessions.restore( sessionId // string )
Parameters
sessionIdstring. A string containing the session ID for the window or tab to restore. This can be found in thesessionIdproperty of theTaborWindowobject in theSessionreturned fromsessions.getRecentlyClosed().
Return value
A Promise. This will be fulfilled with a Session object representing the session that was restored.

Examples
This restores the single most recently-closed session, whether it's a window or tab:
function restoreMostRecent(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);
}
browser.browserAction.onClicked.addListener(function() {
var gettingSessions = browser.sessions.getRecentlyClosed({
maxResults: 1
});
gettingSessions.then(restoreMostRecent, onError);
});
