Convincing Kubernetes to Trust a Backend

They’ve recently added efficiency mode, which is handy until it starts sleeping the tab that Octoprint is on, which queues up all the “live view” features and somehow makes them replay at super-speed when I go back to the tab. AAAAANNYWAY. I did some searching and couldn’t find the answer to “how do I stop Edge from sleeping pinned tab” because that’s not a thing (article on what can stop a tab to sleep here). [Read More]
