From settings, I went to Safari, Advanced then Website data.
Websites are listed in order of decreasing KB.
What determines the KB size? Is it about the website, or does it reflect the traffic from my computer to the website?
Wow, the google sites take 10 times the KB of anything else.
So what does the KB number represent, please? Is it an amount cached on my computer from / by websites that are visited?
Just understand what the numbers represent. So thank you, XXXXX XXXXX you have answered my question.
Have a good day ....
