Firefox Script Errors

Post  Admin on Sun Jan 23, 2011 9:45 am

Warning Unresponsive script
Firefox may give you a "Warning: Unresponsive script" prompt that says "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." This article describes why this could happen and possible solutions and workarounds.

This error is telling you that Firefox thinks that a script may be running out of control and would make Firefox hang if nothing is done. The script could be something on a web page you're accessing, in an extension you installed, or even Firefox itself.

Webroot Spy Sweeper can cause this problem. Disabling Spy Sweeper's Tracking Cookies feature (or disabling Spy Sweeper altogether) can solve the issue.


Letting the script run longer
If you find that pressing the Continue button brings up the same dialog again, letting the script run longer won't help you; it will just make Firefox hang for longer. However, if you can use Firefox normally after pressing Continue, then the script may just needs extra time to complete.

To tell Firefox to let the script run longer:

1.In the Location bar, type about:config and press EnterReturn.

◦The about:config "This might void your warranty!" warning page may appear. Click I'll be careful, I promise!, to continue to the about:config page.

3.In the Enter integer value prompt, type 20.
4.Press OK.
