Powerapps Model driven app keeps asking for Authentication in Firefox

[Billy_C]

Hi,

I don't know why but suddenly im unable to enter my model driven application in firefox.
I am able to go to make.powerapps.com and press the play button for the model driven app.
When the window opens up i see the app layout for a split second and then it says this: "Some components of this app require you to sign in to continue.".
I tried to press the sign in button but nothing happens, I even logged out of my Microsoft account and back in but none of it worked...

This only happens when I am using Firefox, so far no issues inside chrome.

Any ideas what's going on?

Thanks in advance!

Hi Billy,

I've noticed this issue recently, It may be that Firefox isn't handling the auth token refresh well. Something I've found to work, though, is to go to something else which triggers the same authentication process (e.g. a canvas app), authenticate there, and then go back to the model-driven app.

Hi @RobHardy,

I already tried to do this, and I just tried it again. When opening the canvas app it does indeed ask for authentication once but when I switch back to the model-driven app it still asks me to login so I'm afraid that it doesn't work...

Thanks for the tip nonetheless!

Kind regards,

Billy

Having same issue.  Chrome sometimes gets same initial error as Firefox, click sign in, auth window briefly pops up and goes away, then get "Sign in to Continue" pop up, click Sign In, and seems to authenticate normally.  Firefox simply loops.  Having this issue with Dynamics, and authenticated on another tab to M365.  Edge ok.

Started with one user in Chrome 9/22 but self-resolved as described above.  Another user reported today (10/9) in Firefox.  Cache clearing/incognito mode doesn't change anything/

Getting the exact same issue with Firefox. Had to get my team to switch to Chrome for things to work properly.

So I found out what the issue is.

It seems with Firefox you need to enable Microsoft Single Sign On in the settings area. See below url for more details.

@Mick282 oh wow, that's the first time I heard of the fact that firefox had windows Single sign on.
That indeed seems to have solved the issue, although it feels counterintuitive since well if you have to switch accounts you are obligated to add it as a windows account just to use it in the browser.
I don't think that this should have been a thing a browser should be standalone and not intertwined with a device account. I mean if you gonna use firefox on mac or linux and use powerapps its probably still going to fail then.
Unless they intend for it to work like apple you want to something from apple use apple, you want to use something from Microsoft use Windows otherwise you're screwed or that's how it feels (and I don't like that feeling).

Nonetheless issue solved Thx man!

Thanks @Mick282, you are a gentleman and a scholar!

Agree with @Billy_C here though.  This seems really counter-intuitive.  I mean, if I want my users to be more integrated with Windows, I'll have them use Edge.  They use Firefox, Chrome, Pale Moon, etc because they DON'T want that integration limiting other functions.

I have only noticed this behaviour after our organisation enforced restrictions on what users could do on personal devices (e.g. preventing download of data), though I can't say that there's a direct link. As part of this, though, we were advised to enable Microsoft Single Sign On suggests, which I did (this might be why authenticating to something else worked for me).

The main reason I use Firefox, though, is because it allows me to create multiple separate profiles, where I am authenticated different users (not the one with which I log into my laptop). Many of us have admin accounts, test accounts, etc., which we use as part of our daily work, and I find switching users in Edge to be klunky at best.

I hope we are not going back to the bad old days of having to log in to our devices as admin in order to work.
