Dualsense gamepad works through Steam but not detected by Firefox
I'd like to see my gamepad inputs visually on a gamepad viewer/input display site like gamepadviewer.com, but Firefox doesn't seem to detect my DS5 gamepad at all. The gamepad is connected via USB-C and works perfectly with Steam games. I'm using the flatpak version of Firefox on a wayland session, and FlatSeal shows that Firefox should have access to all devices, so I'm not sure what's going on. Any help/ideas would be appreciated.
Solution
I had to add /run/udev:ro to the filesystem section to get my gamepad inputs in firefox
