My firefox is installed in the location: C:\Program Files\Mozilla Firefox. Am trying to read the firefox version like this: 

open (IN, "\"C:\\Program\ Files\\Mozilla\ Firefox\\firefox.exe\" --ver
+sion|") or die "Couldn't fork - $!\n";
my $aarray = <IN>;
print $fh "=========Array Content========> $aarray <====\n";

close(IN);

This is working perfectly. But, when I put path or command in a variable and try to execute, it fails saying "Couldn't fork" 

my $ffox = 'C:\Program Files\Mozilla Firefox\firefox.exe';

$ffox =~ s/\\/\\\\/g; #Replacing single \ with double \\

$ffox =~ s/\ /\\ /g; # Adding escape character before space

chop($firefoxVer);   # remove last \n chr.

$ffox =~ s/$/\\\"/g; # With the below two commands, massaging the comm
+and to become

$ffox =~ s/^/\\\"/g; # "C:\\Program\ Files\\Mozilla\ Firefox\\firefox.
+exe\"

$firefoxVer = $ffox.' --version|'; # Adding "version|" to the above co
+mmand

$firefoxVer =~ s/$/\"/g;  # and make it look like:

$firefoxVer =~ s/^/\"/g;  # "\"C:\\Program\ Files\\Mozilla\ Firefox\\f
+irefox.exe\" --version|"

open (IN, $firefoxVer) or die "Couldn't fork - $!\n"; ==> Fails

The $firefoxVer variable contains "\"C:\\Program\ Files\\Mozilla\ Firefox\\firefox.exe\" --version|". When the entire command goes into the open command as hardcoded string, it works. But, when it is sent as $firefoxVer, it fails. Please help. Thanks.
