Belén could you please take a look at this?
Thank you.

Comment 2

[Julian Descottes [:jdescottes]]

This timeout is surprising, especially as a permafail.
The test is almost identical to browser_application_panel_start-service-worker.js which runs just fine (takes 11 seconds in the log provided here).

From the screenshot https://firefoxci.taskcluster-artifacts.net/cQpb-3y6RzOo0xR015jsAw/0/public/test_info/mozilla-test-fail-screenshot_ycyckl.png it seems that the debug button is still enabled, as if the prefs dom.serviceWorkers.idle_timeout & dom.serviceWorkers.idle_extended_timeout didn't apply correctly? Or the test is really randomly slow at times on ccov? We skip those tests on debug, so it's hard to compare.

Hi, taking a look at this

Attachment: Bug 1654468 - Disable browser_application_panel_telemetry-start-worker.js on ccov builds

Temporary fix (disable the test in ccov). Try push at https://treeherder.mozilla.org/#/jobs?repo=try&revision=74aaa873fc61490cbb4699a03b74ca2ce9b29bb8 (still running)

[Julian Descottes [:jdescottes]]

Note: it doesn't seem to be perma failing. I see a bunch of successful runs on ccov, eg https://treeherder.mozilla.org/#/jobs?repo=mozilla-central&revision=7916b0f71d694c94cf1b1f33d63408420f842dc5&searchStr=Windows%2C10%2Cx64%2CCCov%2Copt&selectedTaskRun=DRrtz140SlSrMA72ERgyug.0

Logs at https://firefoxci.taskcluster-artifacts.net/DRrtz140SlSrMA72ERgyug/0/public/logs/live_backing.log indicate that the test finished in 2 seconds. Whatever makes this fail is intermittent.
