As of the 25th of september I landed bug 1263722 which adds a PerformanceNavigationTiming entry to the existing performance API. The implementation had a few issues which were fixed in bug 1403926, which also puts this feature behind a pref: dom.enable_performance_navigation_timing
Right now this feature is on by default on all platforms. Other UAs shipping this are Chrome and Edge. Work on Navigation Timing 2 is tracked in bug 1043083. If you find any issues, please file bugs blocking it. Link to standard: https://www.w3.org/TR/navigation-timing-2/ Testing: We have web-platform tests covering this. I'm considering adding more, to ensure proper order, and sane values for all fields - mostly issues fixed in bug 1403926. _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
