I have been using the Brave Browser for some time now and I am impressed. It does seem fast, which is my initial thoughts, but I have not done an in-depth comparison with say Opera or Chrome or Firefox or Safari.
One thing which annoys me when surfing the net (a phrase which seems to be dated) is when popups come up, but also when tracking software is being run on your computer after you have visited a site, Brave is a great way of handling this, blocking or managing it as you please.
I also like the way it is opensource, based on chromium and using the Mozilla licence, and dovetails in with the duckduckgo search engine.
While I haven’t engaged in the BAT system yet it is an interesting idea.
