Why do sites on Safari run up so much memory usage, compared to other browsers?
I will see the warning window across the top of various sites (esp. Facebook), saying it's using a lot of memory, and suggesting I close it, far more often, and sooner, on Safari, than others, like Firefox, Opera, Brave, etc. Why is the browser that's supposed to work the best on Macs, the one that runs up memory usage faster than the others? Seems backwards to me...
