In the end I decided to just replace it with uBlock origin plus some filters [0], [1], [2].
While this solution doesn't add a convenient button in the UI to show the hidden domains and to quickly block them, for some reason this extension didn't work if I had javascript disabled, while the native uBlock one did.
I believe there's also a userscript that does something similar, but I never tried it.
