If this is like what they do on iOS - I hate it. Nothing is as fun as reloading tabs.This is something I really wish they’d add to Safari. Heck, I’d like a per-tab button on the browser’s toolbar, to suspend that tab. And a preference setting for whether tabs started in the background start suspended. i frequently have a lot of tabs open that I want to keep open for context (research for various projects and such), that I absolutely do not want sucking up processor cycles. Safari would be much more efficient with such a feature.
