Earlier quoted context omitted.

Then there is an error. Teams supports FF stable, they have even made efforts to improve support https://www.microsoft.com/en-us/microsoft-365/roadmap?filter...

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.

Why not use stable FF for your business meetings?

Thats also blocked. But what did you expect from a greedy multi-million $ company, that already forces their browser on your system. Yust recently there was a post on here that pointed out how Microsoft forces Edge on their Windows Users. So yeah, what did you expect...

Not just nightly. Stable is blocked as well. Seems we're in the next IE-era.

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_?

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.

Controversial opinion: I used to like Firefox but at some point you have to accept the reality: No developer likes to have 2 backlogs, one for Chrome and one for FF. IMO It's better to adopt Chromium-based browsers and put pressure on Google to avoid letting it become the sole decision-maker about the web.

That's why everybody should support Firefox, and only Firefox. Hey, you wanted controversy.

Looks like someone made a boo-boo it’s simply based on the user agent, w/e string matching they do is too strict they aren’t checking for actual JS/WebASM compatibility or anything like that.

Chrome stable with a non standard user agent doesn’t work on via the windows live url but works through the O365 corporate one, same with Safari Mobile without any user agent modification.

This to me looks like stupidity more than malice, their link doesn’t even recommend Edge but rather Chrome and Safari…

Respectfully, I don't care that you have two backlogs. Support the prevailing web-standards or lose me as a customer. I'm already sick of how much I have to kowtow to large companies because they treat developer time as costly, but user time as free.

Respectfully, a lot of developers don't care about losing a small percentage of users. They will get to focus their effort on Chrome users and increase the service quality for them.

Is it blocking Firefox entirely? At least on an M2 Mac, it shows "Your browser isn't supported" running Firefox v110.0.1.

Works for me on Kubuntu 22.04. Note that the link above directly goes to the error page.

Yeah, I logged in and it still gave the error page after routing to /#go. Same happens on my Fedora machine.

I Wonder what features are used here which Firefox doesn’t support. It is certainly not the serial Interface.
