Apache、Nginx下Font Awesome在 Firefox 中不显示问题解决方法

一、nginx服务器解决方法

服务器使用的是 nginx，要在响应的头部添加 access-control-allow-origin 字段，添加方法是用 add_header 指令：

配置例子:

location /assets/ {
    gzip_static on;
    expires max;
    add_header cache-control public;
    add_header access-control-allow-origin *;
}

二、apache服务器解决方法

font awesome (firefox无法显示 火狐无法显示)cross domain (跨域问题) 

the problem

it seems that, for security reasons, firefox simply don't allow you to use by default a font that is not hosted on your domain, not even on your subdomain. the cdn based websites can be also affected in this case.

the solution

after some investigations, i found out the workaround: set a access-control-allow-origin header to the font.

<filesmatch "\.(ttf|otf|eot|woff)$">
  <ifmodule mod_headers.c>
    header set access-control-allow-origin "*"
  </ifmodule>
</filesmatch>

also, if you are using nginx as your webserver you will need to include the code below in your virtual host file:

location ~* \.(eot|otf|ttf|woff)$ {
    add_header access-control-allow-origin *;
}
