+++ This bug was initially created as a clone of Bug #1335821 +++ Please deploy https://github.com/mozilla/fhr-jelly Looks like push procedure is documented here: https://mana.mozilla.org/wiki/pages/viewpage.action?pageId=33101035#fhr.cdn.mozilla.net%28FirefoxHealthReport%29-Update/Pushprocedure More info: We updated the about:healthreport contents the avoid using deprecated Javascript functions that break the behaviour of the page on Nightly. Expected urls (same as before): fhr v2: https://fhr.cdn.mozilla.net/%LOCALE%/ mobile: https://fhr.cdn.mozilla.net/%LOCALE%/mobile/ unified telemetry/fhr v4: https://fhr.cdn.mozilla.net/%LOCALE%/v4/ The PRs we need on fhr.cdn.m.n: https://github.com/mozilla/fhr-jelly/pull/183 Note: please don't mind the failing CI test on that PR, since it's not related to the change itself but rather to a broken test dependency. The page was tested on Nightly in bug 1417787 comment 8.
