Ok fedifam, I asked yesterday about if there's an online tool to check what ad tracking BS your #browser is leaking and surprisingly got no answer so I got off my butt and hunted it down.
Unsurprisingly of course the #EFF has a tool.
My #duckduckgo browser with #Mullvad #vpn aced it.
How do YOU rate?
