In the first few days of voluntary quarantine, I built a Firefox extension called Exploding Tabs: https://addons.mozilla.org/en-US/firefox/addon/exploding-tabs https://addons.mozilla.org/en-US/firefox/addon/exploding-tab... First, you intentionally add a website (e.g. https://facebook.com https://facebook.com) to the list. Once you open that site in a new tab, a countdown begins. Unless you stop the countdown, the tab is closed once the countdown reaches 0. I've been using this extension myself for a few days now. Up until now it seems ok.
