+1 to everything @weilan says
Also another huge issue is, on Mac I can't work with Opera open. Tried my best to stay with Opera, even tried to install sub 100 version on windows but on Mac I don't know how to do it. My issue on Macbook is this, Opera takes A lot of memory, even without tabs. Now I am writing this from Brave browser. I don't think this is developers fault but a shitty product teams.
