在用Android版Firefox查看博客园首页发现中间区域的字体显示非常大，开始以为是首页css对移动版浏览器支持不好。
后来发现原来这是Firefox for Android的知名bug：
Thanks for the report. This is a known bug in Firefox's code to enlarge text to make it more readable on small screens. For details, seehttps://bugzilla.mozilla.org/show_bug.cgi?id=707195
As a work-around until this is fixed, you can disable text enlargement by changing the "Text size" setting to "Tiny" in the Firefox settings screen.
解决方法很简单：
进入Firefox的“设置”->“显示”->“文字大小”，将文字大小设置为“极小”。
