As of March 14 I intend to turn the IntersectionObserver API on by default on all platforms. It has been developed behind the dom.IntersectionObserver.enabled preference. Chrome is already shipping it since 51.
Manual QA and fuzzing was successfully completed ( https://wiki.mozilla.org/QA/IntersectionObserver). A telemetry experiment run for 7 days, enabling the feature for 10% of our nightly (54 and 55) user population. No crashes or stability issues related to this feature occurred during that time. *Bug to turn on by default*: https://bugzilla.mozilla.org/show_bug.cgi?id= 1321865 *Link to standard*: https://wicg.github.io/IntersectionObserver/ _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
