What internet browser do you use?

I use firefox, no need for anything else, just install some ad blocker and you are golden.
Kids be saying "ow this browser X has ad blocking by default" to that I can just say - yeah sure, I can build ad blocking into firefox, it only takes one dev to make a browser, but a whole team to maintain it.
What I'm trying to say is don't use some random browsers, use Chrome or firefox.
