<pre>Currently it is very hard to debug content blocker rules as we can't discover which rule has been triggered.
The only notification I see in webkit code is:
if (willBlockLoad) {
if (currentDocument)
currentDocument->addConsoleMessage(MessageSource::ContentBlocker,
MessageLevel::Info, makeString("Content blocker prevented frame displaying
", mainDocumentURL.string(), " from loading a resource from ",
request.url().string()));
return BlockedStatus::Blocked;
}
But clearly that's not enough.
It would be great if there was some kind of a callback method signaling about triggered content blocker rule.
Essential information:
1. Main document URL
2. Request URL
3. Content blocker rule (if it is possible to pass the whole rule here).
If point 3 is too hard to implement, you might add an ID property to the rule syntax and pass that ID back in the callback method.</pre>
