Defaults. Install Brave and you're done. Site doesn't work? Report non-working site. Wanna support creators? Top up your Brave Wallet or turn on Brave ads.
I've a limited budget and limited time to tip websites. I ain't gonna tip manually every other rando on the internet. Brave takes care of that. Small amounts, yes, but better than just ad-blocking [yes, website owners have to opt-in to it].
Completely uninformed take follows: Also, Mozilla seems to be trying to ramp up their ads department -- search for Mozilla Ads. And no-one gonna convert because they already have Google Adsense.
TL;DR: Firefox is faster but using recommended tools like uBlock Origin leaves websites without income.
Guest add-ons are free AFAIK. VirtualBox Extension Pack is not.
