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!

Just change your Useragent, Microsoft is a bunch of dummies and didn't even bother to code it in a way that makes sense as a DRM lmfao.

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

I used to freelance for a big corp who used MS teams and provided me with separate credentials, while also having my private MS account, that I occasionally use for other corps I worked for.

It was a hell using it that way. I had to run each one in a private Brave window to be able to work on two different accounts.

I know they only use MS teams, bc their infra is all based on MS, and it probably works fine for them internally. But man, this shit needs to be fixed in some way to account for external people, especially the ones who chose their own stack and work simultaneously with others.

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.

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).

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