One of the nice things about using Chrome as my browser is that the browser tabs are isolated. This means that if a web page crashes the browser, it really only crashes a single tab. However, sometimes a web page becomes unresponsive and eats up resources without crashing the browser tab. In such cases, you will need to know how to kill the browser tab manually.
To kill a browser tab in Chrome, just go to the ‘Window’ menu bar item and select ‘Task Manager’ from the dropdown. Then, find the browser tab in the list and click the ‘End Process’ button. You can also sort by CPU usage, which will bring the browser tabs eating up resources right to the top. Note that Chrome runs the browser tab and the developer tools panel separately, so in some cases you may need to close out the developer panel as well.
