Main

    Open Available Browser      ${SiteUrl}      ${Browser}
    Read Excel
    Close Browser

故障原因

脚本中虽然将${Browser}变量设为了Chrome，但Open Available Browser关键字会自动检测系统中可用的浏览器优先启动，出现Firefox相关报错说明自动选择逻辑命中了系统里的Firefox。Ubuntu 22.04默认预装的snap版本Firefox存在沙箱权限隔离，会导致RPA框架调用时无法访问用户配置文件目录，触发配置加载失败错误。

修复方案

按优先级依次尝试：

替换浏览器启动关键字，绕开自动选择逻辑
将任务中Open Available Browser ${SiteUrl} ${Browser}替换为明确指定浏览器的启动语句，强制使用Chrome：
```
Open Browser    ${SiteUrl}    chrome    options=add_argument("--user-data-dir=/tmp/rpa_chrome_temp")
```
附加参数指定了临时配置目录，完全避免加载本地损坏/权限异常的浏览器配置。
修复本地Firefox权限问题（如果需要保留Firefox作为备用浏览器）
执行终端命令修复snap版Firefox的配置目录所有权：
```
sudo chown -R $USER:$USER ~/snap/firefox/common/.mozilla/firefox/
```
如果修复后仍报错，直接卸载snap版Firefox，通过apt源安装非沙箱版本即可解决权限问题。
校验Chrome运行环境
确保系统安装的Chrome浏览器版本和RPA.Browser.Selenium自动下载的chromedriver版本匹配，如果自动下载驱动失败，手动下载对应大版本的chromedriver放到/usr/bin目录下并赋予可执行权限。
