Release Note Request (optional, but appreciated)
[Why is this notable]:
We expect it to reduce Firefox energy use on macOS. The feature enables the use of quality-of-services classes on macOS so that some background tasks can be moved to lower power cores resulting in a significant effect on Firefox energy use.
[Affects Firefox for Android]:
None
[Suggested wording]:
On macOS, some background tasks will be moved to lower power cores resulting in less energy use.
[Links (documentation, blog post, etc)]:
None
