Needs a Update, otherwise a nice Addon.

Seems the extension don't like colons like in https:// (in htaccess).
It shows only https

Option to show subdomains of the target domain would be nice.

Suggestions needs a little bit improvement, or at least an option to select the purpose of the site, so you receive the correct suggestions.

on facebook.com, mozilla shows for www.facebook.com 0 cookies 2.6 MB local storage and for facebook.com 3 cookies, whereas the plugin shows 0 headers 0 cookies. Hence seems the plugin misses some cases

Well well, I am a developer and used to check headers as per security standard. This plugin helps me to do my work very easily, specilay headers suggestion (It flash message if your header values is wrong).

Millions Thanks to Dev, who took time to build such a wonderful peace of work :)

OWASPガイドラインをチェックしているのもグッドです。

不満点があるとすれば、一回一回クリックしなければならないことでしょうか。
