This is beta version of <a href="https://addons.mozilla.org/ja/firefox/addon/csp-for-me/">CSP for Me</a>.
v.0.3.9 Support multiple profiles. etc.
- Support multiple profiles
- Added create-csp directive to add the CSP header to the response.

Adds/Removes directive or directive-value to/from the existing CSP(content-security-policy) header in HTTP response. Can also add the CSP header if it does not exist. Works on Android as well as on PC.

For some reason, HTML tags that work on other addon pages don't work on this addon's page. So I've put an explanation of this addon on github, so please read that. https://github.com/yobukodori/csp-for-me/blob/master/readme-beta-v039.md
