Does the job. But if you pin a batch file it does not parse it correctly. In my example it skipped any more advanced programming arguments, and went straight to a timeout command within the batch. Compiling as an executable fixed this but I gotta -1 for this. Ill happily submit my batch code.

Also minus 1 for the client, connection check at the beginning, and vagueness surrounding this client. Is it always running as a service? Does it only open with Firefox?

Just want to pin a simple batch file! FF57 in case that matters.
