How to Close a Web Page When Frozen
You use an Internet browser, such as Firefox, Internet Explorer or Google Chrome, to navigate websites and view content online. When a Web page freezes, this is actually the Internet browser program that is freezing. If you are on a frozen Web page and the browser is no longer responding, you can shut down the browser process by using the computer's Task Manager. This will also close the frozen Web page and allow you to re-launch the browser once all instances of the frozen browser are closed.
Click the "Ctrl," "Alt" and "Del" keys on your keyboard at the same time.
Click "Start Task Manager" from the menu. A new window will appear.
Navigate to the "Applications" tab if the tab is not already open.
Click on the name of your Internet browser in the applications list to highlight it.
Click the "End Task" button to close the program. Confirm that you would like to close the browser if you are prompted.
Repeat this process if you have more than one instance of the browser open.
