Why I am getting the "Warning: Unresponsive Script" message box? How to avoid this message box?

When you visit a Website that uses JavaScript, Mozilla Firefox browser may give you a warning message box, saying that: "Warning: Unresponsive Script - A script on this page may be busy, or it may have stopped responding. You can stop the script now, or you can continue to see if the script will complete." You should click Continue to let the script to finish. The warning message box looks like this picture:

This is caused by a configuration setting in Mozilla Firefox, which triggers a warning message when a page script is running too long. If you are using a slow computer, you will be more likely to get this message box. If you want to avoid this message box, you can follow this tutorial to change the related configuration setting.

1. Run Mozilla Firefox, and enter "about:config" in the address field. The complete list of configuration settings shows up.

2. Locate the dom.max_script_run_time setting and double click on it. A small input box shows up.
