Hello,
I am trying to open two pages at the same time, in two different tabs, with WWW::Mechanize::Firefox.

I need to read information in these two pages, and don't want to open them one after the other, as i have to wait a bit of time, for the pages to load.

How could i do this?

Because i need to read information in both at the same time, i thought that i needed to open two www::Mechanize::Firefox objects/browsers at the same time. Is that wrong ?
Here is what i have tried, and the results i obtained :

1. create two different WWW::Mechanize::Firefox objects one after the other.
=> seems to work (at least for opening the two pages in two different tabs), but i get this warning when i create the second browser:
Subroutine MozRepl::__load_plugins redefined at C:/strawberry/perl/site/lib/Module/Pluggable/Fast.pm line 104, <DATA> line 1.
Shall i just ignore it?
Edit : i just tried it again and this time it works without warning... All good, then?

2. get the current browser's Firefox::Application, open a new tab and select it. finally, try to use the Application's browser with Firefox::Application::browser(), and get() a page with it.
=> it gives me this output :
Use of uninitialized value in concatenation (.) or string at C:/strawberry/perl/site/lib/MozRepl/RemoteObject.pm line 835, <> line 3. MozRepl::RemoteObject: : Object has no function get at test_tabs_application.pl line 72.
I suppose it was simply not the right thing to do.

What is the right way to do this?

Here is the code that i used for these two methods:
1. Opening two browsers, one after the other (it seems to work without warning now):

#!/usr/bin/perl 

use 5.012003;    # Perl version requirement

use strict;
use warnings;    #comment before releasing

use autodie              2.10;
use Carp                 1.25;
use Perl6::Say           0.16;
use Readonly             1.03;
#

use WWW::Mechanize::Firefox 0.59;

# where is my Firefox executable ? 
Readonly my $FIREFOX_FOLDER 
    => 'C:\Program Files\Mozilla Firefox\firefox.exe';

my $browser_1 = WWW::Mechanize::Firefox->new(
    # launch Firefox if it is not already running
    launch => $FIREFOX_FOLDER,
);
croak 'Could not initialize the browser' if !$browser_1->success();
say '# Browser 1 is now ready to go';

# open page 1
$browser_1->get( $URL_1 );
croak 'Could not open page 1' if !$browser_1->success();
say '# Page 1 opened';

# start browser 2
say '# now creating a second WWW::MEchanize::Firefox browser';
my $browser_2 = WWW::Mechanize::Firefox->new(
    # launch Firefox if it is not already running
    launch => $FIREFOX_FOLDER,
);
croak 'Could not initialize the browser' if !$browser_2->success();
say '# Browser 2 is now ready to go';

# open page 2
$browser_2->get( $URL_2 );
croak 'Could not open page 2' if !$browser_2->success();
say '# Page 2 opened';
    
# stop the program, so i can check which pages have been opened
say '# done !';
my $stop = <ARGV>;

2. Trying to use Firefox::Aplication::browser() :

#!/usr/bin/perl 

use 5.012003;    # Perl version requirement

use strict;
use warnings;    #comment before releasing

use autodie              2.10;
use Carp                 1.25;
use Perl6::Say           0.16;
use Readonly             1.03;
#

    => 'C:\Program Files\Mozilla Firefox\firefox.exe';

Readonly my $URL_2 => 'http://www.perlmonks.org/?node_id=907951';

# start the browser
my $browser_1 = WWW::Mechanize::Firefox->new(
    # launch Firefox if it is not already running
    launch => $FIREFOX_FOLDER,
);
croak 'Could not initialize the browser' if !$browser_1->success();
say '# A browser is now ready to go';

# open page 1
$browser_1->get( $URL_1 );
croak 'Could not open page 1' if !$browser_1->success();
say '# Page 1 opened';

# open a new tab
my $Firefox_application = $browser_1->application();
my $old_tab = $Firefox_application->selectedTab();
say '# old tab recorded';
my $new_tab = $Firefox_application->addTab();
say '# new tab opened';

# get the new tab's browser
my $browser_2 = $Firefox_application->browser();
say "# new tab's browser ready to go";

# bring the new tab in the foreground
$Firefox_application->activateTab( $new_tab ); # bring to foreground
say '# the new tab is now in the foreground';

# open page 2
say '# Now trying to open the page 2 with get($URL_2)';
$browser_2->get( $URL_2 );
say '# Page 2 opened in new tab';  
    
# stop the program, so i can check which pages have been opened
say '# done !';
my $stop = <ARGV>;
