```

Start at var/search/__init__.py:129 in SetBrowser.set_browser(), then trace its callers in var/search/selenium_search.py, especially get_urls and parse_search_results. Re-run the reported zeus.py command with the listed Zeus, Firefox, and geckodriver versions; done means the search run no longer fails with the FirefoxOptions AttributeError.
