"Appswitch" for switching from bank app to secure verification app (using appswitch) fails with Firefox
As the title says, it relates to an app using "appswitch". When Firefox (for Android) is the standard browser, then it doesn't work (I just see the screen in the screenshot attachment).
I talked to the people making the secure login app, and they said to contact the support for the browser I use (or to switch to Google Chrome, which I'm hoping not to do).
So is this something anyone knows about? Any way to fix, or any plans for a fix (if this is not something I can do myself)?

Hi
I am not sure what you mean. Are you able to provide the steps to reproduce what you are seeing?
This might be specific to Danish bank/government/"anything very secure" apps, since it's regarding the switch to the national authorization app.
Open bank app (https://play.google.com/store/apps/details?id=dk.bec.android.mb1.b00032.prod&gl=US), try to log in, and you'll be prompted to verify using "MitID", click "Open MitID app", then it tries to switch to that app (via the phones default browser using "appswitch").
If that default browser is Firefox, what's in the attached screenshot is shown (sorry, guess it failed to upload the screenshot i the first post before I pressed "post").
Circumventing the stuff that happens through the browser, and manually opening the "mitID" app, I can log in just fine. It's only the part where the bank app (Nykredit) is trying to open the verification app (mitID) when Firefox for Android is the default browser that doesn't work (the "fix" from the tech support was "Use Chrome as default browser").
Thank you for that information and apologies for the delay in responding. I think that you may need to file a bug report or feature request. See File a bug report or feature request for Mozilla products for details.
Thanks, I have done this.
