Brave is FASTER by comparison to other 'blink rendering' browsers and probably the fastest browser out there but,
at the expense of should you need to uninstall it for some reason or other..big problems arise ;) other than the eventual
blocking of blockers.
FF 60+ is bloated and slower than FF ESR 60.x which is a good choice (linux and windoze),
purely down to blocker extension and security only updates. YMMV
