invisuu, you might be able to restore bookmarks from Firefox's own backup. See here: https://support.mozilla.org/en-US/kb/restore-bookmarks-from-backup-or-move-them Also, sometimes passwords can be retrieved using the logins-backup.json file in the Profile folder. Although this would need to be done sooner rather than later. * Close all Firefox windows. * Move logins.json to a backup folder. * Copy logins-backup.json to a backup folder. * Rename logins-backup.json to logins.json. * Restart Firefox. If this doesn't work you can always exit Firefox and then restore the original two files. If you do not know where your Profile folder is, see here: https://support.mozilla.org/en-US/kb/profiles-where-firefox-stores-user-data
