Details

I was running a local build of Firefox and had a session fail to restart - I saw the "Sorry. We're having trouble getting your pages back." screen and noticed in the terminal a JS error was thrown, because presumably that window is undefined since it was unrestorable? Either way, we should expand the check in the getClosedTabCountForWindow function here.

JavaScript error: resource:///modules/sessionstore/SessionStore.sys.mjs, line 3776: TypeError: can't access property "_closedTabs", this._windows[aWindow.__SSi] is undefined
