🦊 DualShock Calibration GUI Not Working in Firefox Firefox Does Not Support WebHID — Switch to Chrome or Edge

This is not a bug. DualShock Calibration GUI uses the WebHID API, which Firefox has explicitly decided not to implement. This is a permanent browser limitation that cannot be fixed by the tool or by any extension. You must use Chrome 89+, Edge, or another Chromium-based desktop browser.

❓ Firefox FAQ

Will Firefox ever support WebHID?

Firefox has explicitly declined to implement WebHID, citing security model concerns. The Mozilla security team published a position stating that WebHID provides access to generic devices and poses risks similar to WebUSB, which Firefox also does not fully implement. As of Firefox 153 (2026), there is no scheduled implementation. This is a deliberate architectural decision, not an oversight.

Can I use a Firefox WebHID extension or polyfill?

No reliable polyfill or extension exists. WebHID requires browser-level USB host access that cannot be replicated by a web extension running in a sandboxed browser context. Extension APIs in Firefox do not expose the necessary USB HID primitives.

I installed Chrome but the tool still shows 'Unsupported browser.' Why?

Verify you are running Chrome on a desktop computer, not Chrome on Android or iOS. On Android and iOS, Chrome uses a different engine without WebHID support. Also check your Chrome version — WebHID requires Chrome 89 or later. Open chrome://version in your address bar to confirm. If you have Chrome 89+ on desktop and still see the error, try disabling all extensions in an Incognito window.
