Then there is an error. Teams supports FF stable, they have even made efforts to improve support

both nighly and stable ff is broken - my mother couldn't access her meeting in Firefox the other day because Teams said "you only have to use Edge or Chrome"

This is absolutely true. There are some types of meetings (likely the ones which are MS Stream-based -- but as a plain user this is impossible to detect) where upon joining you will get the dreaded message about incompatible browser.

I don't know what is "support" for them, but I've never been able to make calls in it. Only the chat function works.

That's what I was thinking too. I have to keep Chrome installed on my Linux machine exclusively to use Teams for voice and video calls, since calls have never been possible in Firefox and the Linux desktop client is so buggy.

Linux desktop client seems to be dead; as of last week, trying to download the deb or rpm package results into 404.

The posted link is to the error page. https://teams.microsoft.com works in FF stable.

Oh wow, I clicked on that link on mobile and was unable to go back. Pressing the back button just redirected to the same page over and over again. Usually you only see that on malicious ad sites.

If you don't know already, long press on the back button solves the problem.

Microsoft's largely useless support site does the same thing. There's something weird afoot in that organization.

Microsoft's tech forum pages have been highjacking the back button for years now. It's really despicable...

Nope - "We're sorry—we've run into an issue."

Doesn't work on stable 110.0.1 (64-bit).

Nope, it doesn't. FF stable on MacOS.

Teams is, was, and will be the absolut worst. They only won, because it's bundled into MSO.

Microsoft has always lived in the same era.

> Seems we're in the next IE-era

Too bad there is no Register or Inquirer equivalent this time around.

The register is still there but they're really pro-big business this time around. Recently there was an piece about how happy we should be with all the corporate Linuxes. Bow to our benefactors :)

I can use Teams on the stable version without any issues. You might have cross-origin cookies disabled, which will stop Teams from working. PS. FF:v110.0.1 (64-bit), macOS: 13.2.1.

Those cookies are disabled by default in Firefox. Are you saying that to successfully use Teams one has to alter their browser configuration to make it _less secure_?

I believe it's website specific. Office 365 Teams (teams.microsoft.com) will request users to grant certain permissions when it's visited.

Oops, sorry. I was using the Office 365 Teams (teams.microsoft.com), which runs ok on FF. I can confirm the Teams for the personal account (https://teams.live.com/_#/unsupportedBrowser) is not supported in FF.

the WebKit Wide Web

Doesn’t work in Safari on default settings either, it complains about disabling tracking prevention. Mo thanks. Also, ITP is a few years old by now, support it already. So more like Chromium Wide Web.

Spoken as if “ITP” is some web standard. I had to look it up:
