Opera 11 - один из самых быстрых и гибких в настройке браузеров. Используя скины, пользовательские панели и другие средства настройки интерфейса, внешний вид которого можно изменять до неузнаваемости. Программа позволяет на лету отключать и включать графику, а также может похвастаться фирменной технологией масштабирования веб-страниц, благодаря которой пользователи браузера практически никогда не видят горизонтальной прокрутки. Браузер Opera разработан, чтобы максимально удовлетворить ваши потребности – будь то эффективная работа, интересные развлечения или самовыражение. В 11ой версии обновилась версия движка Presto до версии 2.8, повысилась производительность программы, появились различные улучшения в Opera Mail, усовершенствовалась CSS производительность и множество других нововведений. Также разработчики сообщают, что новая версия браузера будет проходить Acid3 тест с результатами 100/100. Начиная с версии Opera 11.10, новая версия браузера будет получать кодовое имя. Так, для версии 11.50 выбрано имя "Swordfish".
