 ### APIs
 
 - {{domxref('RTCRtpReceiver.getParameters()')}} and {{domxref('RTCRtpSender.getParameters()')}} are now supported, returning an object that describes the current codecs used for the encoding and transmission of media on the receiver and sender tracks, respectively. ([Firefox bug 1534687](https://bugzil.la/1534687)).
+- {{domxref('Blob.bytes()')}} is supported for returning the data from a {{domxref('Blob')}} as an array of bytes in a {{jsxref("Uint8Array")}} object. ([Firefox bug 1896509](https://bugzil.la/1896509)).
 - {{domxref('MediaKeys.getStatusForPolicy()')}} is now supported for checking whether the CDM module, which is used to decrypt DRM protected content, would allow the presentation of encrypted media data for a "hypothetical" key based on specified policy requirements such as the HDCP version supported by the system.
   This provides an application with a simple mechanism to know in advance whether playback at the optimal resolution will be allowed, without having to create a media key session or fetch a real license. ([Firefox bug 1878714](https://bugzil.la/1878714)).

+
+The **`bytes()`** method of the {{domxref("Blob")}} interface returns a {{jsxref("Promise")}} that resolves with a {{jsxref("Uint8Array")}} containing the contents of the blob as an array of bytes.
+
+## Syntax
+
+```js-nolint
+bytes()
+```
+
+### Parameters
+
+None.
+
+### Return value
+
+A {{jsxref("Promise")}} that fulfills with a {{jsxref("Uint8Array")}} object containing the blob data.
+
+### Exceptions
+
+The method will reject the returned {{jsxref("Promise")}} if, for example, the reader used to fetch the blob's data throws an exception.
