inspired by Using LWP (or some other module) to Dowload HTML with Cookie Session ID I tried to unlock the cookies case of Firefox using perl. I have installed DBD::SQLite but the following code fails to open the DB even if Firefox is closed or if try the readonly flag.

I also tried to make a copy of the DB cookiesTEST.sqlite in the case some lock was there.. but nothing but failures.

use strict;
use warnings;
use Data::Dumper;
use DBI;
use DBD::SQLite;
my $db = $ENV{AppData}.'\Mozilla\Firefox\Profiles\nwk2oixj.default-rel
+ease\cookiesTEST.sqlite';
die "DB file not found!" unless -e $db;

print "sqlite DBD version: $DBD::SQLite::sqlite_version\n";

my $dbh = DBI->connect(qq(dbi:SQLite:dbname=$db,'','',{
                            sqlite_open_flags => SQLITE_OPEN_READONLY,
                            PrintError       => 1, 
                            RaiseError       => 1, 
                              })) or die $DBI::errstr; 
my $sth = $dbh->prepare(q(SELECT * FROM moz_cookies )); 
print Dumper $sth->fetchall_arrayref({});

With FF open both DBeaver and sqlite3 command line utility can access the DB without problem. DBeaver uses jdbc:sqlite driver and sqlite> .version shows SQLite 3.40.0 2022-11-16 12:10:08 so not the 3.39.4 shown by DBD.

I have no sqlite in the path.

Searching I found HTTP::Cookies::Mozilla and I installed it: it comes with a stringy documentation ( yes! adopt it ;) but, lurking in /examples I have found /examples/convert-to-mojo.pl that slightly modified to work on windows (around line 19 my @cookies_files = glob(     $ENV{AppData}.'\Mozilla\Firefox\Profiles\*\cookies.sqlite'); ) accesses the db without any issue.

The module documentation ( scan method not even mentioned ;) says explicitly:

> .. so you will need to have either DBI/DBD::SQLite, or the sqlite3 executable somewhere in the path.

Since I have not sqlite in the path, it should use the very same driver used by my failing script, ie: DBD::SQLite

So why the above code fails?

PS ..and now crack the Chrome cookies jar
