1892400 - Support using the remoting service to send command lines after startup

Status: RESOLVED FIXED

(Toolkit :: Startup and Profile System, enhancement)

Description

[Dave Townsend [:mossop]]

Currently we can only send a command line to a running Firefox in a specific point during early startup. There is nothing stopping us making this available more generally to allow sending messages to other instances at any point during the application lifecycle.

Currently the windows client sends the current process command line which is
potentially an issue since some of those arguments may have been consumed
already. It will also not support sending custom command lines after startup.

This simplifies the call signatures of all versions since this is only needed in unix.

With the new profiles implementation we need to be able to identify a running instance
regardless of whether it was launched as a named profile or not. This changes to prefer
using the full profile path as an identifier falling back to testing the profile name
for backwards compatibility.

I'm not sure what you mean here. If I firefox --jsconsole while firefox is running, that opens the jsconsole in the running firefox.

I mean from a Firefox process. We can launch a new Firefox process yes but that is unneeded overhead.

I see what you mean now. Thank you for the clarification.

Depends on bug 1906260 because https://phabricator.services.mozilla.com/D217569 is part of the patch stack.
