Yeah, no thanks Lol
Brave FTW!
Safari is stable and light for me. I have 100+ tabs opened. Computer operates like its nothing. No fans no heat nothing. I have not tested other browser performance.
That being said, Brave+FF are much more capable and open source. I am sure Safari is finicky with rendering some stuff although not sure if its the site designer fault or Apple Webkit's.
Brave is a fantastic choice lest it is based on the Google Chromium project and its Blink enginge is monopolizing the internet.
I use Safari except for the occasional thing it doesn't work for. Then I go for Firefox.
I bounce between a couple Macs and my iPhone, and using Safari everywhere is nice for a unified history and also iCloud Tabs.
My wife falls into using Chrome on her little retina MacBook sometimes and it slows it down horribly and then I have to remind her to not use it.
Use Brave in light mode/theme. Looks same, operates maybe better with privacy. For free.
