Since 25th February there already are 31 failures. :ddurst could you please take a look?
The test fails very often with patch from bug 1373708 (around 0.2 failures/push on try). To reproduce it locally, running it under rr makes it to fail in ~50% cases. Marco, you've fixed failures of this test in bug 1416142. Could you please have a look at this bug too?
I may not have the time to look into this for at least another couple days, due to piled up last minute issues. I'm also not sure the fix for bug 1416142 may help us here at all. In the meanwhile, it may be useful to check if increasing the timeout of requestIdleCallback helps, since you seem to be able to reproduce the failure more often. It may also be useful to explain the behavior differences to expect with the landing of bug 1373708.

The test was disabled by bug 1417052, so this no longer blocks async JAR bug. > In the meanwhile, it may be useful to check if increasing the timeout of > requestIdleCallback helps, since you seem to be able to reproduce the > failure more often. This didn't help. I tried to increase all timeouts I could find in the test (both window.requestIdleCallback and BrowserTestUtils.waitForCondition). > It may also be useful to explain the behavior differences to expect with the > landing of bug 1373708. The patch 1373708 moves blocking IO to a background thread, so its effect is that it no longer blocks main thread, but delivering of the data from the JAR channel can start a bit later.

AFAICT that is only a partial disable on lin/mac debug. If it would be complete we'd have lost testing of this API completely, and that wouldn't be good. Are those 2 enough to prevent your failures?
I've done few retries on the try server and the test failed twice in 372 runs on windows. This seems to be similar ratio to what's reported in this bug without the JAR patch.
ok, good. I'll also track this in the search team backlog. It's possible the add-ons team figures out something before us, anyway whoever finds something is welcome to help. It would be great to re-enable the test everywhere, since we have reduced CCOV now.
Priority: -- → P2
Whiteboard: [stockwell needswork:owner] → [stockwell needswork:owner][fxsearch]
For now there's no huge emergency and we're short on resources, it will keep being tracked.
I think that this bug has the same cause as bug 1417052. waitForAutocompleteResultAt wait for the presence of a search result at a specific index. However, because other tests can inadvertently pollute the search result set, the test stalls because the menu item at the given position will never match the expected result. I will wait for the patch to bug 1417052 to land, and then remove the skip-if at browser_ext_omnibox.js to see if the issue is resolved.
