Please make sure to do a security review so that this doesn't expose
any sensitive information accidentally. In particular, is there any
way to use this API to use :visited hacks along with timing
information to see if a user has visited a particular URL?

I think we're ok since :visited only affects colors which shouldn't affect render or composite times? Is there someone we should loop in who can give a more informed appraisal?

Summary: Provides an interface for receiving frame performance timing
including composites happening on a separate thread/process. This can
be used to calculate measures of smoothness that incorporate the
effect of async pan and zoom and off-main thread animation.

Bug: https://bugzilla.mozilla.org/show_bug.cgi?id=1158032

Link to standard: https://w3c.github.io/frame-timing/

Platform coverage:  all platforms

Estimated or target release:  Firefox 43 although we might hold off
shipping depending on the state of the spec at that time (there has
been discussion of replacing the buffer-based interface with an
observer interface).

Preference behind which this will be implemented:  dom.enable_frame_timing

DevTools bug:  No specific bug yet but the DevTools team is aware of
our intention to implement and indicated they could use this API.

Other browser support: Blink: in development, soon to reach Canary.[1]
