It "works", but requires far too much manual intervention, with frequent authentication popups, as opposed to just using Chrome/Edge and be done with it.
I'm not ruling out that some of it is due to service misconfiguration by the auth team and service teams, but configuration errors or not, the end user result is the same, Chrome or Edge simply offer the path of least resistance.
Name and shame I say.
I have had an issue with Linux and Microsoft SSO. Though that was more down to IT policies in Azure AD than it was Microsoft SSO specifically.
The only time Firefox was an issue with Microsoft SSO was when I tried to buy Minecraft and something about the Xbox / Minecraft / MS SSO required Edge. But that was one instance out of hundreds of interactions with MS SSO
At some point FF wasn't able to do the user verification under linux (ask for a pin). Even though that's been fixed now, azuread still throws an error.
Chromium on Linux works fine. I haven't tried FF on Windows.
Default setting disable all JS. With JS fully enabled. Still doesnt work.
Using ublock and privacy badger.
I will also say theres another browser that does not work. I believe it is mullwad
Happy FF user for about 10 years and I wouldn't change it even if I worked at chase
I refuse to use chrome and I use vivaldi, opera, brave , edge and mullvad as well. Each has a specific purpose.
But my only general browsing browser is FF.
But the weird thing is that this failure happens only on one computer (running MacOS). I have another, with synced settings & extensions & ublock settings (running Linux) and there it always works?
For a normal, public site, I've not seen any issue.
I have been using it nearly 20 years, and still never seen a site I couldnt use in Firefox. Please somebody prove me wrong so that I dont just think everyone that says this is just doing something wrong!
EDIT: Not sure why I am getting downvoted, am I lying? If someone posts a link that doesnt work on FF I would be happy to concede. But I have been asking this for decades and nobody has ever given me one.

About five-ten years ago, I saw a few problems, but creating a new Firefox profile fixed that.
And using it with multi-account containers is nice too.
Don't you guys love blanket statements?
Curiously, most complaints seem to be from Mac users, and not just for this site, leading me to believe that something different may be going on on MacOS builds or APIs that it has to use there.
Used to work fine on Firefox. But since a few months, behavior has been pretty wonky with blank pages. Works fine on Chromium.
The public page works fine.
