You must think you're very important to tell someone else what not to buy, what their objective is, and which web browser they should use.
I hate ads as much as the next guy and certainly agree with preventing cross site tracking (Firefox Containers, for example), but YouTube isn't free to run. They offer me a way to avoid ads so I take it. I'm not going to be a thief while still using their product.
People bitch and moan about ads yet aren't willing to pay either.
