# yacd > Yet Another Clash Dashboard Note for Firefox user: **yacd** is using the [Fetch (Web) API][fetch-api] to stream chunked API response from Clash to draw the traffic chart. But currently the streaming feature in Firefox needs to be turned on manually. Here is how to: Visit `about:config`, search for `dom.streams.enabled` and `javascript.options.streams`, double click those item to turn them on.
