Bug提交：从版本56开始，汉字变成串符乱码

• 使用平台：PC 系统，win7 64 简体中文
• 版本号：   从版本56开始，直到最新的65版本，全部版本，包括 32bit/64bit，以及esr版本
• 复现概率：100%
• 安全模式：问题依旧
• 问题描述：从版本56开始，直到最新的65版本，汉字显示为串符乱码，而版本56以下，却全部显示正常。
• 复现步骤：全部中文网页
• 问题截图：
• 
  

第一：
火狐浏览器，从版本52开始测试，一直试到版本56, 中文页面汉字全部显示正常，
但是，从版本56开始测试，一直试到最新的65版本，汉字全部变成串符方框，如前图。


第二：
同一系统中其它应用程序，全部正常使用。


第三：
同一系统中，IE，opera，chrome等各种浏览器，各种版本，全部正常。
并且测试了Gecko内核浏览器 Waterfox，也是正常的。




我基本能算火狐的忠实粉丝了，上学时（香港回归那年）就用Netscape Navigator Gold了，
一直到后来的mozilla、火狐，用了很多年的火狐，却从版本56开始，汉字显示成串符乱码。
问题出现已经1年，希望能得到解决，

方便的话参考https://zhuanlan.zhihu.com/p/27314228做下回归测试，因为我们定位不到这个问题

先祝LS新年好。

然后测试到第6个版本之后，就结束了，显示数据不够？



然后我该怎么做？

gui的工具应该可以选择版本，按照你说的，设定回归范围为55-56呢

是，我设定的就是版本55 - 56 。

测试到第5个错误版本的时候，就获取不到其它版本了。

看测试结果，2017-07-21 的版本是ok的，从2017-07-22 开始出现问题，一直到现在。

emmm，gui的regression有可能出现这种情况，你用命令行的方式试一下呢，直接回归这两天

命令行方式结果如下。
