I'm satisfied with Google Chrome with an Adblock Plus. I haven't had any problems with it.
For me it is the best browser ever created so far.
Get my point? A business can be successful if no one's ever done it before.
actually Firefox is the best browser in my opinion, it is a lot smoother and there is more respect for your privacy when you are using Firefox instead of chrome.
but is all a matter of preference and has nothing to do with this topic.
the Brave browser can be a good and a bad project at the same time because usually people are not so willing to see lots of ads even if there is a tiny payment in it.
