Hi, Firefox for Android 68.9.0. Android 9 also replicated on Fennec F-Droid on Galaxy S7 with Android 8.0.0 ---- I'm working on an open source app, and we're getting reports that Firefox's Snackbar implementation for opening a downloaded file appears broken: https://github.com/ankidroid/Anki-Android/issues/5374#issuecomment-638112300 . This is fairly heavily battle-tested code, I don't believe this is our bug, and I've reproduced the issue, but I'm happy to be mistaken. '''Steps (fails)''' * Scroll to the bottom of the page: https://ankiweb.net/shared/info/920300037 * Download * Select "Open" in the snackbar * A significant number of apps appear in the screen * Select our application * We receive an Intent with no data. The extra is "com.android.browser.application_id" `Intent { act=android.intent.action.VIEW flg=0x3000000 hwFlg=0x400 cmp=com.ichi2.anki/.Reviewer (has extras) } ` '''Steps (works as expected)''' * Scroll to the bottom of the page: https://ankiweb.net/shared/info/920300037 * Download * Select the Android Notification Firefox places in the Notification Drawer * A small number of apps appear (our app, file pickers, and zip openers). * Select our application * We receive an Intent with data containing the file (happy days!): `Intent { act=android.intent.action.VIEW dat=content://org.mozilla.firefox.fileprovider/root/storage/emulated/0/Download/WSET_Level_1_Study(14).apkg flg=0x4000000 cmp=com.ichi2.anki/.DeckPicker }` Here is the relevant lines of our Manifest, in case we're doing something silly: https://github.com/ankidroid/Anki-Android/blob/7d83fd251e059269fd5832fd6e30c4fba3a2c95d/AnkiDroid/src/main/AndroidManifest.xml#L104-L172 I don't think you'll need the app to test, but: https://f-droid.org/en/packages/com.ichi2.anki/ or https://play.google.com/store/apps/details?id=com.ichi2.anki or https://github.com/ankidroid/Anki-Android/releases/tag/v2.10.4 Thanks for your time, David
