Thanks Harald.

@softvision-oana-arbuzov could you test this with our Microsoft test account? You'll likely have to create a new meeting. It would be interesting to see what happens when we spoof as Chrome.

@adamopenweb , for me team video call seems to be available only on Microsoft Edge. Spoofing on Firefox Nightly as Edge will allow team video call.

Steps to reproduce:

1. Sign into your Microsoft account (Enterprise).
2. Click "Teams" and click "Create team".
3. Type in the team name and add members.
4. While in the "Conversation" tab click "Meet now" button (video icon).

Note: On Chrome and Firefox Nightly it displays that the browser is not supported.

Tested with: Browser / Version: Firefox Nightly 67.0a1 (2019-01-30) Operating System: Windows 10 Pro

Moving to Needsdiagnosis for further investigation.

@miketaylr, what diagnosis should we realistically do here?

[miketaylr]

That's a good question... I wonder if it wouldn't be better to start a conversation with Microsoft to see what the story is.

[miketaylr]

@wisniewskit can you check if Safari is similarly blocked?

[wisniewskit]

I can't even log into Teams on Safari, I get a "Doh! Something went wrong..." page, and see script errors implying there were 404 errors.

[miketaylr]

Oh yeah, I see that too.

Spoofing on Firefox Nightly as Edge will allow team video call

@softvision-oana-arbuzov Adam and I tried to get a working video call spoofing as Edge in Firefox Nightly, but could only get audio to work. Could you and @softvision-sergiulogigan test again, making a call between Test User 1 and Test User 2? Just replace 1 with 2 for Test User 1, the password is the same.

[adamopenweb]

Also Nils asked if you do get a successful Teams call going on Firefox, if you can save the data from about:webrtc please. Thanks!

[softvision-oana-arbuzov]

@adamopenweb and @miketaylr we managed to get the same results as you did, only audio work (after 20-30 seconds) while spoofing as Edge in Firefox Nightly.

Tested with: Browser / Version: Firefox Nightly 67.0a1 (2019-02-06) Operating System: Windows 10 Pro User-Agent Switcher

While having the call I started Debug Mode and AEC logging from about:webrtc and save the data. aboutWebrtc.zip

[miketaylr]

Thanks @softvision-oana-arbuzov, I passed along the zip.

[nils-ohlmeier]

Looking at the aboutWebrtc page (thanks for that) I Teams rejecting the video from Firefox (it doesn't like any of the video codecs offered) and it accepts only audio. But the audio is also only G.722 and not Opus, so relatively bad audio quality compared to other WebRTC based services.

[karlcow]

so I guess the work of diagnosis is done here. Let's move this to contactready and ping Microsoft about it.

[adamopenweb]

I'm going to set as sitewait, as @nils-ohlmeier has been in contact with Microsoft about this issue.

Firefox is going to remain unsupported for the near future.

[nils-ohlmeier]

Rough estimate was that maybe by the end of 2019 Microsoft might be ready to look at re-enabling Firefox support.

[softvision-sergiulogigan]

The issue is still reproducible on my side.

Tested with: Browser / Version: Firefox Nightly 72.0a1 (2019-10-31) Operating System: Windows 10 Pro

This "browser racism" needs to stop. Microsoft has all the resources in the world to make compatible apps and shouldn't discriminate against people that value their privacy.

[softvision-sergiulogigan]

This is still reproducible.

Somebody made an extension that fakes the UA: https://addons.mozilla.org/en-US/firefox/addon/teams-phone-fix/ . Have we considered a UA override recently, @miketaylr @nils-ohlmeier?

Related, the official page: https://support.office.com/en-us/article/join-a-teams-meeting-on-an-unsupported-browser-daafdd3c-ac7a-4855-871b-9113bad15907

Some browsers, including Internet Explorer, Firefox, and Safari, don’t support Teams calls and meetings.

[nils-ohlmeier]

@digitarald does the addon only result in warnings about an unsupported browser to disappear? I would be surprised if it magically makes audio/video calls work in Firefox.

[digitarald]

I didn't test it, but reviews don't mention any glitches: https://addons.mozilla.org/en-US/firefox/addon/teams-phone-fix/reviews/

[SuperTux88]

Back when there wasn't a Linux client yet, I manually changed the useragent, and it magically made audio/video calls work in Firefox back then, but I can't test it at the moment if it still works.

[wartmanm]

Changing the useragent makes almost everything work - outgoing audio and video work, and so does incoming audio. Incoming video does not (it might be my settings?) I haven't tested screen sharing yet.

Changing the useragent makes almost everything work - outgoing audio and video work, and so does incoming audio. Incoming video does not (it might be my settings?) I haven't tested screen sharing yet.

I had the same experience. Audio seemed to work but video was problematic. I tried to have two of my accounts on the same meeting, one on my Android smartphone and the other on Firefox.

On Firefox I could only see the preview of my webcam. On the Android smartphone I couldn't see the video coming from Firefox running on the PC. I could not also see the Android smartphone video on Firefox.

Audio seemed to work better/ok, but it's hard to test by myself without creating some weird feedback effect.

I made the same experiment on the native desktop client and on Chrome and everything seemed to work fine.

It would be really nice if Microsoft could support Firefox on Microsoft Teams. Firefox is my browser of choice and with all this COVID-19 stuff going on I've had to use Microsoft Teams more than ever and I just hate to have to run a full-blown Electron app for receiving some calls and to join some meetings.

[adamopenweb]

Would like to update that we are working with Microsoft now to get Teams support enabled in Firefox. There are no commitments on when that will be, but I can share that support is moving along in the right direction.

FreeBSD-CURRENT

With user agent overrides applied to Firefox 75.0:

• video (webcam) does work
• microphones do not.

[ameenross]

Actually even audio calls stopped working. I can't tell whether this is because of the update to FF 76 or MS changing stuff.

[ameenross]

Every time I try to use Microsoft stuff they do things to disappoint me.
