Your snippet should work if you add that to the profile user.js file
(*not* in the prefs.js file). You probably also need to set
network.proxy.ssl and network.proxy.ssl_port

No proxy capability has been removed.

I doubt that we want to expose a UI for that. If you want to file a bug,
use the Boot2Gecko::Gaia component in bugzilla.
