在ubuntu16.04下安装了nginx 反向代理php7。，使用的是php7.0-fpm，用chrome访问 phpinfo.php文件正常。但用firfox访问同样的页面，出现空白，也没有状态码返回。静态文件访问正常。
请问这会是什么原因？

nginx的配置

You should look at the following URL's in order to grasp a solid understanding

of Nginx configuration files in order to fully unleash the power of Nginx.

http://wiki.nginx.org/QuickStart

http://wiki.nginx.org/Configu...

Generally, you will want to move this file somewhere, and start with a clean

file but keep this around for reference. Or just disable in sites-enabled.

Please see /usr/share/doc/nginx-doc/examples/ for more detailed examples.
