On Firebug, one can hit "profile", then refresh to profile the load of a page. On Safari the same steps result in a non-profile.
I think this is a duplicate of bug 19246

I don't think this is exactly the same as bug 19426. Bug 19426 seems to be about having a new UI option to start profiling and automatically refresh the page. This bug is about profiling during a reload not working at all, regardless of whether we have a UI option for it.

This bug is useful and bug 19426 will help make it more discoverable.
Timelines now auto-record for the first 10 or 20 seconds after page load start.
