场景是，我下了一套bootstrap的页面，当本地用ff打开某一个html的时候，发现页面上的小图片无法正常显示，一开始我一直以为是bootstrap的字体样式问题，后发现同一个页面，在chrome里却能正常显示，后来到处查找一番，终于发现，是ff的设置问题，只要改一下默认设置即可。

解决方案如下：
Firefox has a strict setting(this) that prevents your HTML file from accessing your web fonts from folders not on the root. This only happens when you work locally and not from files on a server. You have to change a setting in Firefox to display the glyphicons when you develop locally.
-open "about:config" in your address in firefox
-Then search for "security.fileuri.strict_origin_policy" property and change it from "true" to "false". (ignore quotation marks of course)
