This is a guide on How To Fix the “Warning Unresponsive Script” message in Firefox.

You can stop the script now, or you can continue to see if the script will complete.” .

This post will help you resolve this nagging issue in Firefox. To learn more, check the steps below. This issue maybe related to a bugged extension, a misbehaving plug-in, the website you are browsing (javascript issue) or with Firefox itself.

Webroot SpySweeper Issue

If you have SpySweeper installed in your PC, check first if you have the SpySweeper Cookie Tracker enabled in Firefox. Try to disable this feature in SpySweeper and see if the error no longer appears.

Let Website Javasript finish loading

Some website scripts may take longer than usual to load and finish rendering. Giving it ample time to complete this process will usually fix issues with these types of errors.

In the url or address bar, type about:config and press Enter.

You will get this message: “This might void your warranty!”. Click “I’ll be careful, I promise!” to continue to the about:config Search box.

Press OK and if the errors no longer appear, we can be sure that the site script was the culprit.

Install NoScript

If the problem exists in your favorite website and there is no way to avoid this particular domain, install NoScript in Firefox and blacklist the suspected script or disable javascript entirely in the website.

Update Firefox, Plug-ins and Extensions

Updating to the latest versions will most certainly fix issues with your browser. Check if you have outdated plugins or extensions which maybe bugged or leaking precious memory.
