Firefox with four windows and multiple tabs each. One tab a single window of multiple tabs. One tab a second window of multiple tabs. Revert one of those, and then try to revert the second. I just lost every tab in one of them, bar the first. I needed those tabs. You have a serious bug. Uninstalled.
