Since vSphere is strong-arming users from the native client to a web client, is there a setting (or plugin) that will prompt me before closing a specific website. I am aware that I could set the warn me before multiple tab closure option and open a second tab, however when I tend to start researching and troubleshooting down the rabbit hole i end up with multiple browser instances with multiple tabs and id like to not have to start confirming closures dozens of times a day. Yeah I know it sounds lazy but hey, I want this one window to be dedicated to a tool i use a lot and don't want to have to reopen over and over if I accidentally close. :)
