However, sometimes the spoofed, fixed values are platform-dependent. A comment in Gecko’s source code explains why this is the case:
Please see this file from our open-source FingerprintJS library, for a production-ready example.
Another good example of the uniformity approach to minimize fingerprint-able browser surface is the recent changes made to the deprecated navigator.plugins and navigator.mimeTypes features. The WHATWG HTML Standard was updated to reflect Flash deprecation and specified that browsers should always return a fixed list of supported plugins and mime types (depending on a new read-only navigator.pdfViewerEnabled property). Gecko and Chromium have already adopted the change.
Needless to say, Brave does the same thing in three other methods that are used to serialize raw canvas data: CanvasRendering2dContext.getImageData, HTMLCanvasElement.toBlob, and OffscreenCanvas.convertToBlob.
Interestingly, however, this wiki page is currently not fully up-to-date as WebRTC has dedicated settings. Instead, the Client Hints JavaScript API’s getHighEntropyValues method returns accurate information, and the Battery Status API returns fixed values in all cases.
