The browser is based off chrome, so all the chrome extensions work. The setup is pretty easy, just make sure you have a Bitcoin address to cash out to. Depending on the type of CPU you have, mine for example is a quad core...pretty old too. You can either run full, half or off, there are a number of settings you can set so it only mines when the machine is idol for example.

The browser, when not mining is really good and quick too. To be honest I don't use it as a browser as such. It's just something I leave running in the background to make a little BTC plus I like to thrash the shit out of my CPU. I know it's going to cost more in electricity, yep probably. I do this for fun, not to get rich and to see different ways to make a little by doing as little as possible 😁
To grow your mining network and to earn more use the referral link. They say by making the browser default you'll mine more. Remember, this is mining via an algorithm not your standard way of mining.
The min payout is 0.00001. Yes they do payout, they payout twice a day at the moment, until they bring in the auto payment system. At least even though it was a low amount, they did pay me with out any fuss or bother, not like Brave were you know come payout day, shit will hit the fan. 
Please let me know what you think.
