Intent to ship: PerformanceObserver

2017-09-05 Thread Hiroyuki Ikezoe 
As of Firefox 57 I intend to turn PerformanceObserver on by default. 
It's been enabled on nightly by default for 16 months. Chrome has 
already shipped it since 52, WebKit has implemented it since January 
2017, but not shipped yet.  Edge has not implemented it yet, but as far 
as I know they have been interested in.


Bugs to turn on by default on all channels: 
https://bugzilla.mozilla.org/show_bug.cgi?id=1386021


Link to standard: https://w3c.github.io/performance-timeline/

Testing: All web platform tests for PerformanceObserver that do not 
require Navigation Timing 2 
.

Intent to ship: PerformanceObserver

2016-05-23 Thread Hiroyuki Ikezoe 
In Firefox 51 I indent to turn PerformanceObserver on by default. It has 
been developed behind the dom.enable_performance_observer preference. 
Chrome has been shipping it[1]. Their 'intent to ship' is [2].
