"Brave" is a morally bankrupt hustle gnawing at the foundations of civil society; it is a bro-wser spawned by a disgruntled has-been consumed by his ego's unwillingness to accept that his bank account does not reflect his former social standing. It is the rare "creative" endeavour motivated solely by a drive to destroy, and to get rich & even in the process.
Also it's just another Chromium skin, so it wouldn't change anything.
At least brave works, Firefox has been completely useless for me on anything but Windows and Android since the quantum update. It drains battery like nobody's business or screws with UI elements when no one asked it to.
