Is it possible to view HTTP/2 push promise frames in Firefox with Firebug? I'm using nghttp2 to create a small HTTP/2 web proxy and I'd like to be able to view and sent push promise frames.
Firebug (at least up to 2.0.x) only displays normal network requests and requests coming from the cache.
I assume PUSH_PROMISE and other HTTP/2 frames are currently not exposed by the internal Firefox APIs Firebug uses.
