Doesn't show POST data, and isn't accessible anywhere except a status bar button. And it certainly isn't pretty!
Aside from that, it does what it says it will do.

Часто минимум это хорошо! Rated 5 out of 5 stars

После установки:
1 - переводим фокус на страницу (кликнув в пустом месте страницы, а не в полях форм);
2 - нажимаем "Ctrl+/" - для появления панели дополнений, обычно внизу;
3 - кликаем по иконке этого дополнения (обычно справа)...

И появляется окошко с http-заголовками странички!
Предельно просто и действенно. Рекомендую.

This extension really help you to know about http headers and all its details. You do not need to go anywhere deep to findout details of the page. So, I also used as for knowing site is safe and original or anyone has tempered with it.
