This fixture will use a local build if one was found, then it'll look for `GECKO_INSTALLER_URL` and automatically bootstrap it, finally it'll look for `GECKO_BINARY_PATH` and use that (this last part just landed and searchfox hasn't updated yet). Finally if no binary was found it'll return None, so you'll need to add a: if not binary: pytest.skip() If you like, you could create an autouse fixture that does: os.environ.setdefault('GECKO_BINARY_PATH', os.environ.get('BROWSER_PATH'))

If the fixture name is taken from the function name, then a test that references the fixture without defining it as an argument will find the fixture function instead of the value returned by the fixture. Naming it this way means I'd get an error that `binary` is not defined rather than getting a reference to the function.
