That is uBlock Origin intercepting the request and responding with a no-op version of analytics.js

That is a uBlock Origin internal stub to prevent sites that rely on Analytics being there from throwing an error and stop working.

See here: https://github.com/uBlockOrigin/uAssets/blob/415820d7561a5cb...

Looks like it's loading Google Analytics from an extension you have installed.

If you lookup the ID cjpalhdlnbpafiamejdnhcphjbkeiagm in the Chrome web store, you'll see that that's the ID for uBlock Origin.

https://chrome.google.com/webstore/detail/ublock-origin/cjpa...

If you download the CRX file, extract it, and check the file ./web_accessible_resources/59fb24a2d12455d15bea20980e8a6801.javascript (the one being loaded) you'll see that it's just a stub; probably designed as a substitute for Google Analytics that doesn't actually send any analytics data but still defines a few necessary functions to avoid breaking sites which rely on them.

The request never reached google-analytics.com, it was redirected by uBlock Origin to a local neutered script, to minimize page breakage.

Often web pages break because they were created as if network requests to google-analytics.com can never fail, and using a neutered script to expose a dummy API prevents such breakage most of the time.

End result: no need to whitelist google-analytics.com to un-break a page.

Maybe some addon is using it?

Service worker?
