### What happened? It appears a recent ublock origin update has added `/fronten…d-metrics^` to its block list which i've tracked down to the `easyprivacy` list. I understand this is in no way related to grafana, however, i cannot find any documentation nor information about what `/api/frontend-metrics` is, what its used for, why it exists and why i should allow it. Grafana is showing an error pop up on every page despite grafana working perfectly without any issues. This error is misleading and ideally i would like to disable it. ![image](https://github.com/grafana/grafana/assets/12700525/f5a1475e-c3ca-41fd-9fea-214828664885) ### What did you expect to happen? For grafana to not display errors when there is nothing wrong with grafana's functionality ### Did this work before? N/A ### How do we reproduce it? 1. Use a chromium browser (e.g. Google Chrome, Edge) or firefox 2. Install uBlock origin 3. Navigate to any page and observe that grafana places a fetch to `/api/frontend-metrics` and displays the error (which is the problem) in the UI ![image](https://github.com/grafana/grafana/assets/12700525/f5a1475e-c3ca-41fd-9fea-214828664885) ### Is the bug inside a dashboard panel? No ### Environment (with versions)? Grafana: Grafana v11.0.0 (83b9528bce) (docker image) OS: Ubuntu Server 22.04 LTS (aarch64 for rpi) Browser: Google Chrome, Microsoft Edge, Firefox ### Grafana platform? Docker ### Datasource(s)? Prometheus, OpenSearch
