force to launch a specific browser

[numbereleven-a]

Is it possible to make a command for a bat file that would force the path to launch a specific browser that is not the default?

You mean, make --autolaunch run a different browser?

Instead of --autolaunch you can add (for instance) start firefox.exe http://127.0.0.1:7860.

replaced --autolaunch with start firefox.exe http://127.0.0.1:7860.
I get an error "unrecognized arguments"
