Details

In bug 1387169, we are removing XPCOM components with WebIDL equivalents. However, there are XPCOM components that are attached to the content-facing window object. These components are listed in the kInterfaceShimMap array in nsDOMClassInfo.cpp. We need to attach telemetry to these interfaces to track usage. From that data, we can see which components can be removed.
