Does Safari freeze/reloads pages? As far as I can tell, at least to me it just slows down Javascript execution but keeps them open, to the point it messes up with some websites, like this: https://www.vitling.xyz/toys/acid-banger/ https://www.vitling.xyz/toys/acid-banger/ . I never "caught" it reloading pages like the old Chrome Sleeping Tabs extension did. Or do you mean Safari for iOS? I'm thinking of macOS Safari here.
