Is this extension slowing down my app/webpage?

Yes, Mutation Observers can significantly slow your app down. However, they are only active when extension is 'recording'.

Attribute changed to the same value?

If you see things like

"class" changed from "test" to "test"

or

"id" changed from null to null

This can mean one of the two things:

either the new value is wrong (DOMListener can't guarantee that this value is OK) or
DOM was 'touched', but the value wasn't changed (e.g. when you call node.style.display = 'none' on node that is already hidden).
