Add an opportunity to detect applied blocking rule

For now there is no way to detect which rule has been applied in order to filter the website requests.

It would be great if there is a tool to check filtered request to find out the rule and some other useful info. For example, which content blocker contains that rule and what else is blocked by that rule if there are other blocked request
