Just before all the Brave haters on this sub appear telling you Brave is crypto scam etc. - this is all based on lack of research and just blindly following headlines. You can turn off all the crypto features, Brave won’t force you to jump onto crypto train once you download the browser. They had some unfortunate accident of using affiliate links based on the page you’ve been visiting, but they quickly abandoned the idea. The way I see it is they want to somehow make money out of this as developing a browser is not a cheap undertaking. And yes, Brave is an ad company. But they’re trying to do all this in privacy-preserving way, somehow attempting to change how the ad business currently works on the web. However if you don’t wish to get any ads you can opt out (or just never opt in) of all this and enjoy good browser with good privacy defaults and built in adblocker. Brave is based on chromium though. Whether you wish to support chromium dominance on the web is your personal preference.

I know Brave has a feature to turn off inactive tabs to reduce memory consumption. Don’t think Firefox does
