I will defend Firefox before I defend Brave. And I do not even use Firefox.
I use Zen. It is not the most private browser on earth, but it is a real improvement over base Firefox and I love using it. If you want Chromium, Helium is great. Ungoogled Chromium is great. There are good options in every direction. Brave is not one of them.
Brave is not a privacy browser. Brave is a crypto scammer company.
Default install today: BAT rewards, Brave Wallet, Leo AI, Brave VPN, Brave News, Brave Talk, Brave Search promos, sponsored new tab page, built-in torrent client. There are entire community projects whose only job is to ship registry scripts that turn this stuff off. Users debloat a "privacy" browser. Read that again.
And the track record is rough.
2020: Brave got caught auto-injecting its own affiliate code into URLs you typed yourself. You typed binance . us, Brave silently rewrote it to binance . us/?ref=35089877. Same for Coinbase, Ledger, Trezor. Brendan Eich defended it first, called it a mistake only after the backlash. Open source did not save anyone here. The code sat in the repo for ten weeks before anyone noticed.
2018: Brave collected BAT "donations" for Tom Scott and other creators who had never signed up, using their names and photos. When Scott asked for the money back, Brave said refunds were impossible.
2021: Brave's built-in Tor mode leaked every . onion address you visited to your regular DNS provider for months. If you used Brave to hide your dark-web activity, your ISP saw all of it. The bug shipped to stable in November 2020 and only got fixed in February 2021 after a researcher went public.
Use what you love. Zen, Librewolf, Mullvad, Helium, Ungoogled Chromium, base Firefox if you want, even Safari. A browser whose business model is shoving shitcoin and a paid VPN at you is not a privacy product. It is an ad-tech company with better marketing.
