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.

    Actually, one or more of my extensions (probably Adblock) seems to detect some of those banners and block them (more accurately, it asks me if I want to block them, and I just say no). I think it might be based on a curated list, idk.

    Still... yup. Blocking Google Analytics is scriptblocking 101.
