Controller Not Detected in Your Browser?
Reviewed: 31 October 2026
A connected controller can remain hidden from a webpage until you use it while the page is active. Start there, then separate the computer connection from browser detection.
1. Focus the test and press a controller button
Keep the Gamepad Test visible, click the page and press a face button or move a stick. If more than one controller appears, select the one you intend to check.
MDN documents that an already-connected gamepad may first be reported after a button press or axis movement on the focused page. Firefox specifically requires interaction while the page is visible. A missing controller before that step does not establish a connection fault.
2. Check the connection to this device
Confirm that the controller is connected to the computer or phone running the test. Use the connection method supported by your exact controller and operating system. The Xbox Wireless Controller model documented in the official source below supports compatible USB and Bluetooth connections; that does not establish support for every older Xbox controller.
In Windows 11, device controls are under Settings, Bluetooth & devices, Devices. Use Add device and the controller manufacturer's pairing instructions if it has not been connected. A saved Bluetooth entry alone does not demonstrate that a webpage can receive its inputs.
3. Compare USB and Bluetooth where supported
If the controller supports both routes, repeat the check using a compatible USB data cable. Try another suitable cable or port if the connection remains uncertain. A charging light does not prove that controller data is reaching the computer.
For DualSense, PlayStation documents USB Type-C and Bluetooth connection methods. Its controller guidance distinguishes cables that support charging and data from charge-only cables. Follow the official pairing instructions for your model; do not use a reset sequence intended for a different controller.
4. Compare another current browser
Reconnect the controller, reload the test, keep the page active and press a button again. Then compare another current browser on the same device, keeping the connection method unchanged. This is a useful comparison rather than proof of a particular hardware fault.
If the test reports a policy or access error, record its exact wording. Webpages can be restricted by browser Permissions Policy; changing the controller's pairing cannot override that restriction.
5. If inputs appear, check what is actually missing
Once button or stick readings change, the controller is being exposed to the page. A different button label can be a mapping issue. Inspect the raw button values instead of assuming that the diagram must match every controller.
The Xbox Controller Test and PS5 Controller Test provide model-oriented layouts. If the problem is movement while the sticks are untouched, continue to the Stick Drift Test.
Choose the next check
If the controller works in the browser but not a game, review that game's controller support and settings. If it works over USB but not Bluetooth, investigate the wireless connection. If it is missing everywhere, record the model, operating system and connections tried, then use the manufacturer's support route. A successful browser test confirms the exposed inputs in that session; it does not certify every controller feature.
