Thank you for the bug report!

Adding this permission looks like the right thing to do. However, I don't have a gaming controller to test out. Do you confirm your gamepad is mapped to /dev/js*, extraymond?

To clarify: I have a PS4 controller ready. However, my Linux machine detects it as /dev/bus/usb/001/010.

That was on Arch Linux. On Ubuntu 16.04, the same controller is mapped to /dev/hidraw0. Without Snap, I can play [1] on Firefox 60. I'll have the Snap version tested.

Ah, I can't open Tanks on the Snap version of 60.0. The website reads:
> Your browser does not support WebGL

The browser console says:
> Error: WebGL warning: Failed to create WebGL context: WebGL creation failed:
> * Error during native OpenGL init
> * Exhausted GL driver caps.
> * Exhausted GL driver options.

When open in a Terminal, the firefox snap binary returns:
> libGL error: No matching fbCongis or visuals found
> libGL error: Failed to lead driver: swrast

We did declare the "opengl" permission[1]. I don't see any other which can match. Ken, how can I get better logs on this?

Sorry for the long delay!!!
My controller is mapped at /dev/input/js0, and is confirmed working by jstest-gtk.
However there are no gamepads found by calling navigator.getGamepads()

Additional info:
Joystick in snap that enables the joystick interface works fine: for example -> retroarch, so snap's interface is working as expected.

The current version of firefox didn't enable the joystick interface in the snapcraft.yaml.
I think that might be the case.
