The failing part of the test is testRemoveFrameAfterErrorPage which will not load the errorpage, just keep showing about:blank https://searchfox.org/mozilla-central/rev/048146721b3c1a568257afb4325c7a8d94334e2d/docshell/test/unit/test_subframe_stop_after_parent_error.js#114

Comment 21

[Geoff Lankow (:darktrojan)]

Kris is there anything we can do about this failure? It must be something to do with the config difference between Firefox and Thunderbird, but I can't figure out what. I do know that it goes away with browser.tabs.remote.autostart set to false, but that's hardly a solution.

Comment 22

[Geoff Lankow (:darktrojan)]

If we can't find a solution this week I'd like to turn the test off for Thunderbird so we don't have to put up with it for an entire ESR cycle.

BTW if anyone's wondering why the failure count has dropped, we've largely given up marking it.

Comment 24

[Geoff Lankow (:darktrojan)]

Attachment: Bug 1710069 - Disable test_subframe_stop_after_parent_error.js on Thunderbird until after 91. r=kmag,nika

I have very little hope of this test passing on Thunderbird before 91 moves to beta. Therefore I'm turning it off to reduce the noise on what will become comm-beta and comm-esr91.

Comment 25

[Nika Layzell [:nika] (ni? for response)]

(In reply to Geoff Lankow (:darktrojan) from comment #21)

Kris is there anything we can do about this failure? It must be something to do with the config difference between Firefox and Thunderbird, but I can't figure out what. I do know that it goes away with browser.tabs.remote.autostart set to false, but that's hardly a solution.

I believe that is the cause of this issue. Firefox always runs xpcshell tests with browser.tabs.remote.autostart = false, even though we don't ship Firefox with e10s disabled.

Comment 26

[Geoff Lankow (:darktrojan)]

Then I think all we can do is disable the test (or fix it to work with e10s). We can't stop Thunderbird tests running with the default preferences, and we can't override e10s in the manifest.

Comment 27

[Magnus Melin [:mkmelin]]

Alternatively the test could check browser.tabs.remote.autostart and bail out if it's true.

Bug 1710069 - Disable test_subframe_stop_after_parent_error.js on Thunderbird until after 91. r=kmag,nika

Beta/Release Uplift Approval Request

• User impact if declined: Just disables a test that fails when run in Thunderbird. We'd like to clear the failing test from TaskCluster so that failures we're actually concerned about aren't missed.

Please note that I screwed up the original patch so two changes landed.

• Is this code covered by automated tests?: Yes
• Has the fix been verified in Nightly?: No
• Needs manual test from QE?: No
• If yes, steps to reproduce:
• List of other uplifts needed: None
• Risk to taking this patch: Low
• Why is the change risky/not risky? (and alternatives if risky):
• String changes made/needed:
