Summary: We've already got the performance resource timing API implemented (https://bugzilla.mozilla.org/show_bug.cgi?id=822480), but never got around to implementing the user timing API. This would allow users to set unique marks for profiling events in their own code, and most of the objects already exist, we just need to expose/store them in the right way. There's some performance tools being developed for FxOS that polyfill this API, but it'd be nice to just have it done.
