Now that the security review in bug 1542229 and the follow-up work that came out of it is complete, we should go ahead and flip the remote.enabled preference. This patch causes the remote agent to be available to users on the Firefox Nightly release channel. This meansusing --remote-debugger will no longer cause a fatal error Differential Revision: https://phabricator.services.mozilla.com/D55137 --HG-- extra : moz-landing-system : lando

Building
The remote agent is included in the default Firefox build, but only ships on the Firefox Nightly release channel:
% ./mach run --remote-debugger
The source code can be found under remote/ in central.
There are two build modes to choose from:
Full build mode
The remote agent supports only Firefox, and is included when you build in the usual way:
% ./mach build
When you make changes to XPCOM component files you need to rebuild in order for the changes to take effect. The most efficient way to do this, provided you haven’t touched any compiled code (C++ or Rust):
% ./mach build faster
Component files include the likes of components.conf,
RemoteAgent.manifest, moz.build files, and jar.mn.
All the JS modules (files ending with .jsm) are symlinked into
the build and can be changed without rebuilding.
The remote agent’s startup code found under remote/startup/
is written in Rust and requires rebuilds when changed.
You may also opt out of building the remote agent entirely by setting
the --disable-cdp build flag in your mozconfig:
ac_add_options --disable-cdp
Artifact mode
You may also use artifact builds when working on the remote agent. This fast build mode downloads pre-built components from the Mozilla build servers, rendering local compilation unnecessary. To use them, place this in your mozconfig:
ac_add_options --enable-artifact-builds
