Teams apparently can't call when using Firefox

Well they are just lying, it works fine with Firefox and has worked fine for years. I live in the EU though. Sucks to be american these days, I guess?

Just one more upside to Firefox, less interruptions during work~

Its cool how all these companies are allowed to just lie to you about their products functionality.

This team block is so agressive to firefox users that it's literaly hardcoded as if web browser firefox then deny.

You cam override that by changing a parameter in firefox to advertise itself as another we browser. I don't remeber how i did it but, once i had to use firefox and i just changed that stting in order to advertise me to the host as a edge browser. With that changed i could use teams as normal.

Epic drm.

This is not mildly infuriating this is the free internet being eroded through Google’s control of Chrome

This is likely legacy code. Firefox used to have a lot of issues with WebRTC, so practically all video conferencing systems blocked it. Teams probably has some "block Firefox because it doesn't work properly" check that was written 5+ years ago and none of the current developers are even aware of its existence.

Well-coded ones did feature detection instead of checking the user-agent, meaning they automatically started allowing Firefox as soon as it implemented all the required features.

Feature detection is usually the way to go. If your website / webapp depends on a particular feature, check if that specific feature exists, rather than checking for particular browsers. Browser checks are still needed in some cases, for example Safari sometimes reports that it supports particular features but it really doesn't (or they're so buggy to the point where they're unusable), but that's relatively rare.

Try changing your user agent to a Chrome one (e.g. Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/120.0.0.0 Safari/537.36). Works a treat!

Ms teams sucks in a big way

Teams won't even open on Safari. Must use a chrome-based browser (like... Edge!)

given the love Teams receives, it not working in [ insert browser ] is definitely a feature

Have you tried changing your user agent string to Chrome? I know it can sometimes sidestep these types of "errors". It can be changed manually through about:config under general.useragent.override, or there exists plenty of addons to switch it more easily.

You can make it work by changing your UserAgent string (there's plugins for that) to some older chrome version to make things work.

I works for me without a user agent change if I enter through the Microsoft 365 teams workspace and not a teams share link.

I just had to switch to New Teams last week because Classic teams just continued to have more and more call drops and connection problems. The New Teams doesn't even have an option to change the notification sound, and now I can't move the banner that appears in the top center of the screen when screen sharing that covers up tabs in browsers and the main preferences/search dialog in VS Code...also a Microsoft product. Apparently no one at Microsoft noticed that one of their most used products used in the most normal way blocks out important functionality from another one of them.

Im sure if you swap user agent to chrome they wouldn't give a fuck

Teams also doesn’t support multiple “work” accounts

Firefox lets you have completely separate profiles with separate accounts (URL: about:profiles, it can't be linked to for security reasons) and also an official extension to have another layer of profiles on a per-tab basis (containers).

It really can't. If you spoof the user agent it'll crash immediately after a call starts.

I suspect they use something extra on top of normal WebRTC.

The other issue I have with conferencing apps on browsers is that they request access to your microphone even if it's a one-way audio session (i.e. webinar). It should be set in a way where you can separately join a meeting with audio without allowing access to your microphone.

I feel validated, reading about my daily struggles with Teams.

You can use multiple work accounts in the app, have some clients that have their clients give them accounts to communicate internally with them. Just have to keep switching.

I'm in Linux, I had so much problem with FF and Teams that I installed Edge and Teams as a PWA, no more problem with calls and video

On a bullshit teams call right now. I'd call it not working a feature 😄

can't, or won't?

Remember when Internet Explorer/Edge was only used to download Chrome. Well, ironically these days I only use Chrome to make video calls.

yet

Pfft!

use teams classic, most professional workspaces are switching to it since the "new" teams came out

I read this whole thread and didnt find a single person who uses teams inside ferdium like me.

Microsoft made their minecraft website complete in functional for Firefox. You can't even download the launcher without chrome.... And I don't understand why. What in the world do they need chrome features that Firefox hasn't?

I use floorp, it has user agent spoofing. Set it to chrome, works like a charm.

Jitsi is better

Works fine for me in Firefox.

It's never worked on FF for me. I installed Chromium just to be able to log into several Teams accounts. And tabs are still not working. Classic Microsoft mess.

Neither can slack.

they want you to use edge and hook you onto gpt for a while 😆

Its telling you to use the webapp. https://teams.microsoft.com

You cant share your desktop in it last i used it, but calls did work.

Reason?

1. Firefox does not support Microsoft Teams
2. Microsoft disabled support for Firefox
3. Problem for a specific computer/account

You can use private mode or a different browser to login with multiple Teams accounts.

Yeah, as far as I know it's not some browser chauvinism, but Firefox not supporting some multimedia protocols, that doesn't mean it's Firefox fault though, I'd install some chrome fork just for this kind of interactions
