WebRTC application developers can now specify a target in milliseconds of media for the jitter buffer to hold. WebTransport is built on top of QUIC/HTTP3 and provides reliable streams and reliable and unreliable datagrams.

WebTransport is expected to see widespread use for media delivery and other applications. It's expected to ship to release in the near future. Starting with Firefox 113, the WebTransport API is now enabled in the Nightly channel, including RFC 9297 support. This command is available only when designMode is set to "on" or there is at least one editable element which has contenteditable attribute, and the built-in editor has not handled the insertParagraph, delete, or forwardDelete command. This new behavior can also be enabled by web apps themselves for all channels with a call of document.execCommand("enableCompatibleJoinSplitDirection", false, "false") (introduced in bug 1810663). Similarly, when two nodes are joined, the built-in editor deletes the latter node and moves its children to end of the preceding node. When a node is split, the built-in editor creates new node after the original one, i.e., creates the right node.

Starting with Firefox 113, Nightly and early beta builds now behave similar to the other browsers when splitting a node (e.g., typing Enter to split a paragraph) and joining two nodes (e.g., typing Backspace at start of a paragraph to join the paragraph and the previous one) when using the built-in editor.
