I only use Brave for my school work and to watch netflix, everything else I do on FF. If you feel like FF is slow compared to chromuim based browsers, you should try and optimize/harden FF and see the differences for you.
Personally FF is alot lighter and faster for me than Brave for searching the web and Is what I choose to use in the background when I play games because of how light it is compared to brave.
Also since your using Brave you should turn on “Upgrade connections to HTTPS” to Strict! Just a recommendation!
Have a nice day!~
Oh okay, thanks for the reply I understand what you meant now!
