Mozilla Firefox 58.0 Beta 78今日发布，此版本与之前引发轰动的57一样，同样采用Quantum引擎，大大提升了浏览速度，新版引入了WebVR的支持，此版本在旧微码下的Intel Broadwell-U处理器平台上运行可能会有崩溃的bug， 还需要注意的是升级到新版后，原有的Firefox配置文件可能会不再支持覆盖降级，因此您可能要将Profile目录备份后再行测试，不然会引发设置丢失，扩展工作不正常等问题。

Downgrading profile to previous versions is not supported. In case of downgrade, it is suggested to use a new profile
Unresolved
On Windows and Linux, Firefox crashes occasionally on Intel Broadwell-U processors with old microcode . Windows users should ensure Windows Update is set to install updates. Linux users should ensure that the distribution package for Intel microcode is installed.
