使用selenium调用firefox提示Profile Missing的问题解决
在Ubuntu22.04环境中，使用python3运行selenium提示 Profile Missing， 具体信息为：
Your Firefox profile cannot be loaded. It may be missing or inaccessible
在这个问题的环境中firefox浏览器工作正常。
排查中，手动在命令行执行firefox可以打开浏览器，但是出现如下提示
Gtk-Message: 15:32:09.944: Not loading module "atk-bridge": The functionality is provided by GTK natively. Please try to not load it.

事实证明，在这个环境中使用apt-get install libcanberra-gtk-module命令来安装软件包并不能解决问题。
主要的原因在于：
自Ubuntu 22.04开始，Firefox可能默认以Snap包形式提供，对于Snap版本的Firefox，配置文件路径通常位于：/home/$USER/snap/firefox/common/.mozilla/firefox/ 这个目录下，因此相关的代码变更如下：
原代码：
from selenium import webdriver
driver = webdriver.Firefox()
driver.get("http://www.baidu.com")
更新后的代码
from selenium import webdriver
from selenium.webdriver.firefox.options import Options
from selenium.webdriver import Firefox
firefox_options = Options()
firefox_options.add_argument('-profile')
firefox_options.add_argument('/home/xxx/snap/firefox/common/.mozilla/firefox')
driver = webdriver.Firefox(options=firefox_options)
driver.get("http://www.baidu.com")
特此记录一下
