I have just started to use Microsoft Edge, what lured me in was the "auto sleep tabs"-feature. Chrome is eating an incredible amount of memory if you are a tab junkie like me. I have used an extension called Tab Wrangler for a few years to keep thing under control but the Edge sleep feature is more coinvent and always good to not have to use an extension.
Anyway, when i was trying to figure out if there was a way of closing all sleeping tabs in Edge (seems like it's not possible atm) i realized that i can "Shift-Click" tabs to select multiple tabs and close and them all at once. It seems that this works in Chrome as well. A bit embarrassing that i had no idea about this.
