How do I add a 2nd search bar like FireFox has

Hello, I’m new to this Brave thing.

Can you add a 2nd search bar? Does Brave have extensions/themes like FireFox has?

And lastly, what’s the deal with people getting paid for using Brave? Is that real money?

No. As far as I’m aware of.

Yes. Chrome extension/theme should work well with Brave. https://support.brave.com/hc/en-us/articles/360017909112-How-can-I-add-extensions-to-Brave-

It’s called utility token. Once earned, can be used to support creators/publishers via Brave Rewards. Or if you want, you can withdraw (convert to fiat) and/or redeem a reward like gift card, etc.
