After reading an article here on HN, I gave Brave a crack for a week but returned to my regular browser. The thrill of dopamine hits from earning a BAT oken for viewing a brave-blessed ad for the underprivileged wasn't worth changing a browser for.
A "drop in replacement for Chrome" just isn't my thing as a Firefox user - I just didn't love the browsing experience otherwise.
If the company were to expand their market for postive-ads and crypto coins by releasing a Firefox plugin as a "drop in replacement for uBlock Origin" it might tickle my fancy.
