The popular content blocking extension uBlock Origin blocks CSP reporting on websites that make use of it if it injects neutered scripts.

CSP, Content Security Policy, can be used by web developers to whitelist code that is allowed to run on web properties. The idea behind the feature is to prevent attackers from injecting JavaScript on websites protected by CSP.

CSP reports any attempt of interfering with the site's policies in regards to scripts to the webmaster. This happens when users connect to the site, and is used by webmasters to analyze and resolve the detected issues.

[...] Raymond Hill, the developer of uBlock Origin, replied stating that this was not a bug but by design. The extension blocks the sending of CSP reports if it injects a neutered Google Analytics script.

    So yes, you may need multiple users to hit different subsets of the documents on a site.

    Multiple!= all. All non-UBO users should be sufficient.

    If the majority of your users end up using other ad or script blockers that have the same bug as UBO, that could cause poor coverage as well.

    It's not a bug. It's a properly implemented security and privacy feature.
