Just like your Windows PC, your browser has its very own task manager, which you can use to monitor the various processes it is undertaking and how much resource it is diverting to each. To access the manager in Windows, click the hamburger in the top-right corner and select 'More Tools->Task Manager'.
Once you open the task manager, you will see all the plug-ins, extensions, and tabs that are currently in progress, and you'll also see how much of your browser's resources each process is using (like memory and image cache).
