This is a failure that I have seen also on v2.0 and I want to investigate this.
I cannot reproduce this locally manually or via automation.

I don't think the changes in the PR will influence the issue from https://bugzilla.mozilla.org/show_bug.cgi?id=1028236#c0

I investigated this issue a while ago and could not reproduce it locally. It seemed to be related to the internet connection issues.

Started an adhoc run without the changes to see if it still fails:

The adhoc run was green even without the change. The original issue may have been caused by a slow internet connection.

r- this PR doesn't bring additional value to the test.

I agree with this. We're not interacting with this element so it's not important that it be displayed. We're just using it as an event.

Usually when this test has failed in the past thre are a lot of errors in the logcat so that should be the first place to check.

[Florin Strugariu [:Bebe]]

Andrei can you take a second look over this?

Comment 10

[[:AndreiH]]

Bebe, when I run this locally it passes every time, so it's hard for me to see the errors in the logcat, if there are any.

Robert, Vio, did this fail anytime from the last week?

Comment 11

[Robert Chira [:RobertC]]

I have not seen this fail on v2.0 this week or on v2.1 last week.

Comment 12

[Viorela Ioia [:viorela]]

The test didn't fail on v2.1 this week either.

Comment 13

[[:AndreiH]]

Thanks for the info guys, guess I will be closing this if it did not fail for the past two weeks.
