CSP for Me 作者： yobukodori

Adds/Removes directive or directive-value to the existing CSP(content-security-policy) header in HTTP response. Works on Android as well as on PC.

Usage
See the screenshot.

• Enable at startup: Enable this feature when the browser is started.
• Print debug info: Output debug information at the bottom of the Options tab.
• no-cache: Controls the Cache-Control header so that CSP-modified pages are not cached.
• Theme: Select a color theme for the settings page. As soon as you select a theme, it will be reflected in the settings page, but only temporarily. Apply or Save as needed.
• Applied URLs: Comma-Separated target URL patterns.
• Applied Policy: CSP directives to add or remove.
  Add: Follow the CSP syntax.
  e.g. script-src 'unsafe-inline' https://yobukodori.github.io
  
  Remove: 'remove':<value> or <regular expression> or 'directive'
  e.g. script-src 'remove':https://www.google-analytics.com 'remove':/^'(nonce|sha256|sha384|sha512)-/; report-uri 'remove':'directive'
  
  Remove CSP header itself: When no-csp is written as an original directive, the CSP header itself is deleted.
  e.g. no-csp
  
  Adds new value to end of existing value if same directive name exists.
  Adds new directive to end of header value if same directive name not exists.
  Does nothing if CSP header doesn't exist in response.
• Save: Save and apply settings.
• Apply: Apply settings. (doesn't save settings).
• Get Status: get current status and applied settings.
• On enables this feature. Off disables this feature. Or clicking lock icon in toolbar will bring up a pop-up menu where you can turn it on/off and open the settings page.
• Clear Log: Clear log.
• Export Settings: Export settings to the file. It is the currently applied settings that are exported, not the saved settings.

If CSP for Me doesn't work, reload the page several times. The browser may be loading the cache of the page before CSP modification.
