1824710 - Browserstack doesn't work in nightly

Status: RESOLVED FIXED

(Web Compatibility :: Site Reports, defect)

Description

[Emilio Cobos Álvarez (:emilio)]

[Tracking Requested - why for this release]: Browserstack is a common way for developers to test other browsers.

Bisected to: https://hg.mozilla.org/integration/autoland/pushloghtml?fromchange=03dee83a03904f370c3539e78f3977ca6012ac4a&tochange=73fca811cf6ef5a9ed1ec3ac8c83b42e75366c38

STR:

• With an account (I can help with that) go to https://live.browserstack.com
• Select iPhone, and choose Safari, I was setting Safari 16 on iOS 14.

ER:

• The emulator loads and I can test it.

AR:

• Infinite waiting screen. This is on the console on the bad case:

Uncaught TypeError: attachMediaStream is not a function

Set release status flags based on info from the regressing bug 1510802

Comment 2

[Byron Campen [:bwc]]

The JS console errors are not being helpful at all, since they indicate errors that have been invalid for a long time. However, I see mozRTCPeerConnection in their js code, seemingly being used for user-agent detection. That interface has been deprecated for nearly a decade, with console warnings, and we finally removed it in the regression range. This is very likely a site issue.

[Dennis Schubert [:denschub]]

I poked David Burns, who should be able to help us get this looked at on their end.

Comment 5

[Byron Campen [:bwc]]

I've verified that bug 1531812 is where this broke; this is definitely due to reliance on that mozRTC API.

[Byron Campen [:bwc]]

I've also reached out via their support, and pointed them at this bug.

[Tracking Requested - why for this release]: correcting flag from prior edit.

Comment 9

[Ryan VanderMeulen [:RyanVM]]

Moving this over to the Web Compat product where I believe this should live. I guess we could potentially ship an intervention if we had to?

[BugBot [:suhaib / :marco/ :calixte]]

The bug is marked as tracked for firefox113 (nightly). We have limited time to fix this, the soft freeze is in 9 days. However, the bug still isn't assigned.

:denschub, could you please find an assignee for this tracked bug? Given that it is a regression and we know the cause, we could also simply backout the regressor. If you disagree with the tracking decision, please talk with the release managers.

This has been deployed to BrowserStack prod.

Thank you all, BrowserStack is working again for me in Firefox Nightly.

Thanks for helping get this in front of the right people, David!

Closing as fixed. Thanks so much, David! <3
