> It is really a shame that basic functionality like this isn't built into more browsers and we have to rely on extensions to fill the gaps just to keep memory usage under control for tab-a-holics like myself. :( The way I see it, extension developers get to come up with innovative new features first, and then the first-party vendors like Apple, Google, and Microsoft take note and eventually do just that: Integrate it into their own products. For example: The Great Suspender → Sleeping Tabs [experimental] (Microsoft/Edge); Flux → Night Shift (Apple/iOS); Growl → macOS Notifications (Apple/macOS); Swype → iOS Built-in Keyboard (Apple/iOS); etc Edit: Fix formatting.
