Send args to Firefox when launching from terminal Additional arguments on start of Google Chrome from Terminal app are send in a following way:

open /Applications/Google\ Chrome.app   --args -myArgs="ARGS"


What is the syntax to sending arguments to Firefox?

Tried the obvious:

open /Applications/Firefox.app   --args -myArgs="ARGS"


This runs the Firefox, but the args are not set.
In order to pass arguments to an application opened by the open command, use both the -a and the --args options.

Example: open -a Firefox --args -private-window

From the open man page: open [ −a application] file ... [ −−args arg1 ...]
