Report-Sample-Injector od Emanuele Uliana

This addon edits the incoming CSP header(s) to include the 'report-sample' value for the 'script-src', 'script-src-elem', 'script-src-attr', 'style-src', 'style-src-elem', 'style-src-attr', and 'object-src' (although currently unsupported) directives, only if the specific directive is present and does not include 'report-sample', and the directive 'report-uri' is present with an endpoint specified.

This addon is aimed at helping website owners/developers filter incoming CSP reports.
