```

Start with var/search/__init__.py around SetBrowser.set_browser and then follow its caller in var/search/selenium_search.py. Reproduce the reported `zeus.py -r -E -W` command with the listed Firefox and geckodriver versions, and inspect the Selenium newSession failure. Done means the search flow handles this environment without the unhandled exception.
