Firefox 是否允许使用 "aggregated" 火焰图分析 JS 应用程序？
Does Firefox allow profiling JS apps using "aggregated" flame charts?
Firefox Developer Tools 支持 flame charts，但似乎时间被用作 X 轴：
In the Flame Chart view itself, along the X-axis is time. The screenshot above covers the period from 1435ms to a little past 1465ms. Along the Y-axis are the functions on the call stack at that point in time, with the top-level at the top, and the leaf function at the bottom. Functions are color-coded to make them easier to distinguish.
火焰图通常使用百分比作为X轴，例如：pyflame or Brendan Gregg's flame graphs.
我发现基于时间的火焰图令人困惑，并且无法获得每个函数的聚合时间（类似于 Call Tree as far as content is concerned, but represented in more visual way). Also, if a function is short but is called many times it is easy to miss it, while on "aggregated" flame charts it would stand out prominently. To see why time-based flame charts are confusing, let me borrow example from - 不可否认在 Chrome 中，但问题是相似的：
即使某些功能占用了总时间的 30%，也不会在上图中显示出来。
有什么办法（通过插件或设置）让 Firefox 显示选定时间片的聚合火焰图而不是基于时间的火焰图？
似乎 extending the DevTools 相当有限，除非您正在创建自己的面板，但您实际上无法访问其中的分析器来生成您的火焰图。
您仍然可以将记录的配置文件保存到 JSON 文件中，对其进行解析，然后创建您自己的可以计算总聚合运行时间的火焰图。
您也可以尝试 Gecko Profiler Add-on 进行一些更高级的分析。不过，您将处于同一条船上，因为您需要将其导出以对配置文件数据进行自己的聚合。
