And that makes the pageshow handler in browser.js that examines content.document throw because content is null. JS stack to the relevant swapFrameLoaders callsite: 0 swapDocShells() ["chrome://global/content/bindings/browser.xml":1155] this = [object XULElement] 1 _swapBrowserDocShells() ["chrome://browser/content/tabbrowser.xml":1956] this = [object XULElement] 2 swapBrowsersAndCloseOther() ["chrome://browser/content/tabbrowser.xml":1914] this = [object XULElement] 3 anonymous() ["chrome://browser/content/browser.js":8500] this = [object Object]
