I've been using brave. I like ad free YouTube. Idk if it's the best.

internet explorer

There's no good answer to this right now

Basically you should be using Tor browser at maximum security settings, but nostr still doesn't have a client you could use then, so unless you're a high tier nostr dev + web admin, there's not much you can do

I am using Brave 😁

Brave, Opera (both supporting IPFS), Brave supports TOR .onion sites as well

waterfox is my choice

I’m using Brave and Zen Browser
