This may be fixed in the newest version of AC, but we haven't gotten new snapshot for Fenix, so maybe it's just because we haven't gotten a new snapshot.

Let's keep a pulse on this over the next few days but it seems to have disappeared?

I think the issue is still there, I able to reproduce it on master, the issue happens when the input has an image mime type.

STR:

1. Go https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input/file
2. Toggle Desktop site (to be set ON).
3. Tap browser button below the label "Choose a profile picture".

I'm taking a look to how to fix it. I will keep you update.

I think the main issue rely on feature-prompts and Fenix providers has the same authorities properties: android:authorities="${applicationId}.fileprovider"

Feature prompts
https://github.com/mozilla-mobile/android-components/blob/master/components/feature/prompts/src/main/AndroidManifest.xml

Found the source of the issue the android:name="androidx.core.content.FileProvider" property is the same is both case and it should be unique.
