Comment (by gk):

 Replying to [comment:7 rah]:
 > I'm wondering whether there is a simple switch to activate this
 functionality in the tor-browser branch?  Or is it a matter of the code
 not being there yet?

 I think you should have access to `document.timeline` if you switched `dom
 .animations-api.core.enabled` to `true`. At least for me it was available
 to content then as well.
