I'm not having any issue on Firefox Preview 2.3.0, @sv-sdeiac can you check from your side if the problem still persists?

[sv-sdeiac]

I am still able to reproduce this issue on the latest version of Firefox Preview 3.0.1 #13502256 using Google Pixel (Android Q).

Can we try testing this on lower-end devices? Does this also occur in Nokia 6 in the latest build? Also, are you using an emulator or a physical device?

On my Asus Zenfone Max pro m1, Android Pie, it seems to work fine. I also upgraded my Preview to 3.0.1 and still there is no sign of this bug.

Hello @obitodarky, I retested this issue on the latest version of Firefox Preview 3.0.1 #13502256 and I can confirm that is reproducible 100% using the following devices:

• Nexus 5 (Android 6.0.1);
• Huawei P9 Lite (Android 7);
• Nokia 6 (Android 7.1.1);
• Motorola Moto G6 (Android 8).

Also, I wasn't able to reproduce the issue on LG G7 fit (Android 8.1).
I want to specify that all my investigation was performed on the physical devices, not an emulator. If I can help you with other information, please let me know, thanks.

Hi, this issue is still reproducible using the latest version of Firefox Preview Nightly 4/9 #21000923.

Device:

• Samsung Galaxy Note 8 (Android 9).

Reproducible on latest Nightly 6/11 with Nokia 6 (Android 7.1.1) with one update: "Remember decision for this site" is not checked after the front camera is requested.
If it is checked, the popup is not displayed anymore.

It could be an Android version specific issue as tested on Pixel 3 with Android 10 Nightly 6/11. I wasn't able to simulate the issue.

Perform additional testing on different Android versions that I have available:

• Huawei MediaPad M2 (Android 5.1.1) - reproducible
• Nokia 6(Android 7.1.1) - reproducible
• LG G7 FIT (Android 8) - not reproducible
• Xiaomi Redmi Note 8T (Android 9) - not reproducible
• Samsung Galaxy Note 10 (Android 10) - not reproducible

This is a gv bug. I filed this ticked for it

[BranescuMihai]

Note: besides the bug from GV, I think there's also a different problem regarding how we store the permissions. Since this is an ASK_TO_ALLOW permission, we don't save it to disk, but there's no memory storing it either. So when you switch the camera on the same site, it will always prompt you to accept.

I have a fix for that, but I'm waiting on the GV fix, in order to re-check

Thanks @BranescuMihai for the help :)

For temporary permissions (when the use didn't check the checkbox), we are not storing the result neither on disk nor on memory to follow the same behaviour as desktop and Fennec. For example in desktop and Fennec if a permission is granted and again requested by the site both browsers prompt again. Please, verify and let me know what do you think :)

You could test using https://talky.io/ and switching cameras or microphones.

[BranescuMihai]

@Amejia481 you're right, I checked the behaviour on Desktop and it's the same. However, on Chrome(both Desktop and Android), they do not ask permission for every camera/microphone switch, so it feels smoother for the user, maybe we should consider doing the same on both platforms.

Sidenote: For phones with pop-up front camera, such as OnePlus 7T Pro, it's even weirder, because grant always calls the callback, it goes into a loop where the camera pops up and down continuously
