uBlock Origin at a minimum. But I would suggest a privacy focused browser. Librewolf, Mulvad or even Brave. Browsers leak so much information about you it is easy for sites to fingerprint and track you even with an ad blocker.

I know Librewolf is working on their DNS leakage (last section on privacytests.org), but they also allow you to select a privacy focused DNS server which is nice when you’re not on a network you own, so you can’t run PiHole.

It’s had to have been 25 years since I last heard about them.

edit: just hit their Wikipedia page and saw Beto O’Rourke was a member!

I just finished building mine from KB-3D. Can’t recommend them enough. Their customer service is almost always around on the Voron discord and answered every stupid question I had along the way.
