+        If [disabling uBO](https://github.com/gorhill/uBlock/wiki/Quick-guide:-popup-user-interface#the-large-power-button) makes the issue go away, then in all likelihood this is a filter issue.
+        See [what the logger reports](https://github.com/gorhill/uBlock/wiki/The-logger) reports when you reproduce the issue, this will help you determine whether this is a filter issue.
+        If the issue is still present after wholly disabling uBO in the browser, then the issue is unrelated to uBO.
