Most operating systems have a built-in task manager or resource monitor that allows you to see all the active processes and programs running on your computer. Chrome web browser also has one that helps you get rid of troublesome tabs and extensions.
Open Chrome Task Manager
To open the Chrome Task Manager, click the More button (three dots), hover over More Tools, and then click Task Manager. Alternatively, press Shift + Esc on Windows or Search + Esc on Chrome OS to open the Task Manager.
Now that the Chrome Task Manager is open, you can see a list of all the tabs, extensions, and processes currently running in the browser.
End of troublesome processes
You can end any of the processes from this menu, which can be useful when an extension or tab stops responding. To do this, click on the process and select End Process.
You can kill more than one process at the same time by holding down the Shift or Ctrl key (Command on Mac), highlighting multiple items from the list, and then clicking the End Process button.
