The same page in Google Chrome in incognito mode downloads and processes Matomo / Friendly without errors in the console.

Vivaldi is used as the more privacy friendly alternative which additionally provides European digital sovereignty to Google Chrome, just like Friendly.

This error can be ignored safely.
