Hi,
I’m pretty new to the program called Fiddler, so maybe I don’t unterstand it right.
I had this programm running in the background and opened a site in Brave (Build in Adblocker settings are on "Aggressive).
As you can see in the screenshot, Domains like Google Analytics, Doubleclick etc are all in that list…
In Firefox with uBlock Origin, there’s not a single ad or tracking domain.
