#309 - Closing unused tabs in browser to reduce CPU and energy usage

I noticed that the fan of my laptop was very loud at some point. I wondered what was going on and looked in the task manager (on Windows laptops you can press Ctrl+Alt+Delete on the keyboard and then choose Task manager) to see which process was taking a lot of CPU capacity. It was my browser, so I decided to close tabs I didn’t need anymore. This helped a lot and therefore reduced energy use.
