The firefox snap declares a plug on the joystick interface (https://snapcraft.io/docs/joystick-interface), which should enable detecting and using your gamepad.
It's not auto-connected though. Can you try: snap connect firefox:joystick Then restart firefox, and test again? ** Changed in: firefox (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/1962403 Title: Gamepads are no longer detected Status in firefox package in Ubuntu: Incomplete Bug description: After the upgrade from Firefox deb to Firefox snap, my gamepad is no longer being detected. One gamepad is a Feitun FM0013, a gamepad with at least 5 operation modes I've found so far: Nintendo Switch Pro Controller, X-Box wired controller, PS3 wired controller, PS3 wireless controller and generic Bluetooth controller. From these 5 operation modes, X-Box wired controller, PS3 wired controller and generic Bluetooth controller work on my computer, while Nintendo Switch Pro Controller mode is found but doesn't detect any buttons while using PS3 wireless controller mode isn't found. When using on my notebook and smartphone, I normally use this gamepad in generic Bluetooth controller mode, as I want to use it wirelessly more often. I have noticed that any of the modes that worked with Firefox deb (X-Box wired controller, PS3 wired controller and generic Bluetooth controller) stopped working with the snap. Steps to reproduce: 1) Have Firefox installed as a snap; 2) Connect gamepad with one of its compatible modes; 3) Access page/game to test the gamepad (https://hacks.mozilla.org/2013/12/the-gamepad-api/ or https://luser.github.io/gamepadtest/ or http://www.cross-code.com/en/start for example); 4) Notice how the gamepad isn't detected. I have a Redragon Seymur 2 too, and it also isn't detected. Using the Firefox from the Mozilla page, the gamepads are found and appear as follow in the luser's page: gamepad: 0079-0006-DragonRise Inc. Generic USB Joystick gamepad: 045e-028e-Microsoft X-Box 360 pad The X-Box 360 one is the Feitun. Using Bluetooth, the Feitun appear as: gamepad: 1949-0402-Gamepad So, unfortunately, Firefox snap is unusable to play games while using gamepads. For example, I can play CrossCode on the Chromium snap, but am unable to play it on Firefox snap.
