Where does selenium script pick browser from

I am using Windows and I have a perl based selenium script with the following statement :

$sel = Test::WWW::Selenium->new( host => "localhost",
                                port => 4444,
                                browser => "*chrome",
                                browser_url => $ARGV[0]/" );

So, I need the firfox browser to open up a custom profile. To do that i have configured a firefox shortcut with the -P "profilename" appended to target. Now how do i make Selenium open the firefox browser using the custom firefox shortcut. Is there an environment variable that i can set up to include the path of the custom shortcut to ensure that the browser thrown by my Selenium script uses the firefox profile that i need.

P.S. I cannot change the call to Test::WWW::Selenium->new to include the absolute URL of the browser.

i am facing the run the script at local host, how can i resolve it .

Using selenium script with chrome and Firefox browsers are same
here syntax's for firefox browser is

Code:

my $driver = Selenium::Firefox->new;
$driver = Selenium::Firefox->new( marionette_enabled => 1 );
 
#Do stuff...
 
$driver->shutdown_binary;
 
# For Firefox 47 and older, disable marionette:
$driver = Selenium::Firefox->new( marionette_enabled => 0 );
$driver->shutdown_binary;

Profile page opener in Firefox

Code:

my $profile = Selenium::Firefox::Profile->new;
my $firefox = Selenium::Firefox->new(
    firefox_profile => $profile
);
