Selenium启动Firefox报错：Process unexpectedly closed with status 11

环境与代码 #

Python脚本 #

"First selenium script"
from selenium import webdriver
from selenium.webdriver.firefox.service import Service as FirefoxService
from webdriver_manager.firefox import GeckoDriverManager


driver = webdriver.Firefox(
    service=FirefoxService(executable_path=GeckoDriverManager().install()))

.driver.get("https://www.google.com")

控制台错误输出 #

已尝试但无效的操作 #

• 将/usr/local/bin中的GeckoDriver移至脚本所在的~/selenium目录并设置路径参数
• 执行sudo chmod -R 777 ~/selenium/修改权限
• 通过about:support重置Firefox并禁用所有扩展

解决方案 #

1. 修复脚本语法错误 #

脚本中.driver.get("https://www.google.com")多了一个前置句点，正确写法应为driver.get("https://www.google.com")，这个语法错误可能直接导致进程异常终止。

2. 严格匹配Geckodriver与Firefox版本 #

状态码11多数由二进制文件版本不兼容引发崩溃，需确保两者版本严格对应：

• 查看本地Firefox版本：执行firefox --version
• 下载对应版本的Geckodriver，替换现有文件后赋予执行权限：chmod +x geckodriver

3. 临时禁用Firefox Sandbox测试 #

Nobara基于Fedora，可能存在Sandbox权限冲突，可添加启动参数绕过：
修改脚本添加FirefoxOptions配置：

from selenium.webdriver.firefox.options import Options

options = Options()
options.add_argument("--no-sandbox")

driver = webdriver.Firefox(
    service=FirefoxService(executable_path=GeckoDriverManager().install()),
    options=options)
driver.get("https://www.google.com")

注意：禁用Sandbox会降低安全性，仅用于排查问题，生产环境不建议使用。

4. 安装缺失的系统依赖 #

Fedora系统可能缺少Firefox运行所需的依赖包，执行以下命令补全：

sudo dnf install -y firefox-libs alsa-lib dbus-glib gtk3 libX11 libXcomposite libXdamage libXext libXfixes libXrender libXtst nspr nss

5. 使用系统包管理安装Geckodriver #

避免webdriver-manager自动安装的版本不兼容，直接通过dnf安装适配系统的版本：

sudo dnf install -y geckodriver

修改脚本直接调用系统路径的Geckodriver：

driver = webdriver.Firefox(service=FirefoxService(executable_path="/usr/bin/geckodriver"))
