```

Start with var/search/selenium_search.py, especially get_urls at line 84 and parse_search_results around line 268, then reproduce the issue with the reported zeus.py command and environment details. Trace the Firefox/Geckodriver failure and define the expected behavior for this search operation; done means the command no longer ends with the reported unhandled Marionette exception.
