Apa cookies itu?

Cookie adalah serangkaian teks yang disimpan pada komputer Anda oleh situs web yang Anda kunjungi. Pada umumnya cookie menyimpan pengaturan atau preferensi Anda untuk suatu situs web tertentu, misalnya bahasa yang dipilih, atau lokasi (negara) Anda. Ketika Anda kembali ke situs web tersebut, Firefox akan mengirimkan cookie yang bersesuaian kepada situs web yang bersangkutan. Dengan cara ini, situs dapat menampilkan informasi yang sesuai dengan pengaturan atau preferensi Anda.
Cookie dapat menyimpan berbagai jenis informasi, termasuk di antaranya informasi pribadi seperti nama, alamat rumah, alamat email, atau nomor telepon Anda. Akan tetapi informasi ini hanya akan disimpan jika Anda pernah memberikan informasi ini kepada situs tersebut. Situs web tidak dapat mengakses informasi yang tidak pernah Anda berikan kepada situs web tersebut, dan situs web juga tidak dapat mengakses berkas lainnya pada komputer Anda.
Secara bawaan (default), aktivitas menyimpan dan mengirim cookie tidak pernah terlihat oleh pengguna. Akan tetapi, Anda dapat mengubah pengaturan Firefox sehingga Anda dapat mengizinkan atau menolak permintaan penyimpanan cookie, menghapus cookie yang tersimpan saat Firefox ditutup, dan lain sebagainya.
