[Kelly Cochrane [:kcochrane]]

Can we please verify this is resolved after a fix last night in bug 2030988?

Comment 21

[Ryan VanderMeulen [:RyanVM]]

Bug 2030988 didn't actually un-skip the test though.

Comment 22

[Kelly Cochrane [:kcochrane]]

(In reply to Ryan VanderMeulen [:RyanVM] from comment #21)

Bug 2030988 didn't actually un-skip the test though.

It was already unskipped in a previous bug (bug 2030772) specifically here: https://phabricator.services.mozilla.com/D296210

Comment 23

[Ryan VanderMeulen [:RyanVM]]

Would be good if we uplifted those fixes to Beta. It's still frequently failing there.

Comment 24

[Kelly Cochrane [:kcochrane]]

Just requested uplift for beta if it's not too late.

Comment 25

[BugBot [:suhaib / :marco]]

The patch landed in nightly and beta is affected.
:kcochrane, is this bug important enough to require an uplift?

• If yes, please nominate the patch for beta approval.
  • See https://wiki.mozilla.org/Release_Management/Requesting_an_Uplift for documentation on how to request an uplift.
• If no, please set status-firefox151 to wontfix.

Beta uplift occurred for two depends on bugs here.
