This is one of the simplest and cheapest (for free if you know where to go) things for your computer.
Basically, this creates an extended desktop to drag and drop other browsers or programs allowing you to do multiple things at once without clicking back and forth

Step 1: Find a Monitor
You'll need a computer already with a monitor and then need to find a separate monitor.
