回国的时候最麻烦就是访问国外的网站：邮箱、油管视频等。在中国大陆，翻墙是违法的，但是好像在上海北京等大城市，可以申请许可，比如一些国际驻公司和政府机构因需要则可以申请绕过大墙网GFW/Great Firewall。
翻墙/建梯子的方式很多种，怕麻烦可以买现成的VPN，自己有服务器的可以建Wireguard等。这里再介绍一种简单的方式。
Docker容器里跑火狐FireFox浏览器
假设你的主机/服务器/VPS里已经装有Docker。只需要把下面的脚本存成一个BASH文件，比如 docker-firefox.sh 然后在命令行下跑：./docker-firefox.sh PASS 其中PASS是密码，这个我们下面要用到，PASS如果不写的话则要把 “-e VNC_PASSWORD=” 那行删掉即可。
#!/bin/bash
VNC_PASS=$1
docker run -itd \
--restart always \
--name=firefox \
-p 5800:5800 \
-v $(pwd)/config:/config:rw \
--shm-size 1g \
-e ENABLE_CJK_FONT=1 \
-e VNC_PASSWORD=${VNC_PASS} \
jlesage/firefox
等一会儿，这时候Docker会去拉取这个软件镜像，然后完事即可在浏览器里把你的 域名/IP地址 后加上5800端口， 5800是上面脚本里指定的，也可以改成你想要的端口。
输入这个脚本命令Docker就会加载容器 jlesage/firefox
这样跑起来了，你的主机就相当于一个中转/代理，你在国内的时候访问你的主机（如果你主机没被大墙网拉入黑名单的话），那你就可以在浏览器里的内嵌FireFox浏览器里打开其它国外网站了。
在浏览器里输入服务器IP/域名(HTTP)后加上 :5800 端口号 还需要输入刚刚指定的密码。
使用体验
可能是和我的主机配置有关，总觉得有点卡。不是很流畅。还有就是我想登陆我的GMAIL帐号，被GOOGLE认定有风险，要我改密码，吓得我只能作罢。
试了一下，看了一个油管广告，没有声音，所以通过这个技巧看油管视频是不现实的。
还有就是，目前只支持HTTP，而不支持HTTPS，如果域名开启了HSTS，那只能通过IP来访问HTTP。不过，你可以通过nginx/apache设置一个反代 reverse proxy 来访问HTTPS。
比如以下是在Nginx服务器配置443端口重新转向到这个FireFox代理：
server {
listen 443 ssl;
server_name domain_name
ssl_certificate /root/fullchain.cer;
ssl_certificate_key /root/key.key;
location / {
proxy_pass https://your-server-ip:5800;
proxy_ssl_verify off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
}
这玩意不适合日常工作，但是回国用于救急还是可以的。特别是不想在公共电脑上留下痕迹，只需要用强密码+HTTPS。等不需要用的时候记得把Docker容器删除即可。
docker stop firefox
docker rm -f firefox
这个没法支持多用户，也就是说多个用户同时登陆看到的是同一个窗口。
测试可以在浏览器里打开谷歌
可以使用：docker logs -f firefox 来查看窗口的相关信息：
