Mozilla Firefox发布版本上geckodriver的默认日志级别设置为INFO级别。您的框架或您正在使用的语言绑定（Java）可能会覆盖默认设置。
我们可以将日志级别设置为以下任一级别：
All CONFIG FINE FINER FINEST INFO OFF SEVERE WARNING 以下是将日志级别设置为 OFF 的代码块：
package demo;
import java.util.logging.Level;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.firefox.FirefoxOptions;
public class Gecko_TRACE_LOGS
{
public static void main(String[] args)
{
System.setProperty("webdriver.gecko.driver", "C:\\Utility\\BrowserDrivers\\geckodriver.exe");
FirefoxOptions options = new FirefoxOptions();
options.setLogLevel(Level.OFF);
WebDriver driver = new FirefoxDriver(options);
driver.get("https://stackoverflow.com");
System.out.println("Application opened");
System.out.println("Page Title is : "+driver.getTitle());
driver.quit();
}
}
