How to Fix “Warning:Unresponsive Script“ in Firefox [Updated]
Last updated on May 31, 2014 By Venkat
Update : This is worth the try.
Install YesScript extension which lets you block JavaScript that is causing problem on specific websites.
Install the add-on, restart the browser, open its options and add the page/site on which warning is appearing to block that script.
Let me know this is working for you or not through comments.
Recently, while I was browsing certain websites and reading mails in Gmail, got unresponsive script warning in Firefox, it caused Firefox to hang and give that warning message.
This warning comes due to several reasons as Firefox unable to handle java script on that website you are browsing, and may cause Firefox to hang that’s why Firefox asks to either to stop the script or continue the script on that page.
But neither stopping the script, nor continuing the script does not yielded any favor, I got the same warning again while browsing those sites.
The reasons could be due to Add-ons installed in Firefox or the java script in webpage you are accessing or Firefox it self.
Since this Script warning comes to me when browsing Gmail and couple of websites, I suspected Firefox, since the Firefox version using is outdated and also Firefox stopped the support to Firefox 2.0 (Only one computer in network is using Firefox 2.0 and remaining are updated one’s).

One way to avoid this is to wrap your poor performant piece of code with a timeout like this:
This is not a bullet proof solution, but it can solve the issue in some cases.
When JavaScript code runs for longer than a predefined amount of time, Firefox will display a dialog that says Warning: Unresponsive Script. This time is given by the settings dom.max_script_run_time and dom.max_chrome_script_run_time. Increasing the values of those settings will cause the warning to appear less often, but will defeat the purpose: to inform you of a problem with an extension or web site so you can stop the runaway script.
Finding the source of the problem
To determine what script is running too long, click the Stop Script button on the warning dialog, then go to Tools | Error Console. The most recent errors in the Error Console should identify the script causing the problem.
Checking the error console should make it pretty obvious what part of your javascript is causing the issue. From there, either remove the offending piece of code or change it in such a way that it won’t be as resource intensive.
EDIT: As mentioned in the comments to the author of the topic, Firebug is highly recommended for debugging problems with javascript. Jonathan Snook has a useful video on using breakpoints to debug complex pieces of javascript.

When JavaScript code runs for longer than a predefined amount of time, you see a dialog that says Warning: Unresponsive Script. This time is given by the settings dom.max_script_run_time and dom.max_chrome_script_run_time. Increasing the values of those settings will cause the warning to appear less often, but will defeat the purpose: to inform you of a problem with an extension or web site so you can stop the runaway script.
Complete Error Message:
“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.” Sometimes the message mentions an extension, which may or may not be causing the problem: «Script: chrome://fastdial/content/storage.js:71»
Anything that causes the mozilla application to slow down can cause this warning to be issued. The slowdown may be caused by an extension, but it might also be a web page, another program, or resource utilization (CPU, memory, disk IO) at levels high enough to impact one or more application.
Contents
Finding the source of the problem
Click the Stop Script button on the warning dialog, then depending on your version, go to Tools > (Web Development) > Error Console. The most recent errors in the Error Console will identify the script that was running. But note, in some cases the add-on/extension causing the problem is not the one identified in the messages.
Extensions
Unresponsive Script is often caused by a recently installed extension, or an update to the extension or application thus causing some incompatibility between the two.
Disabling extensions or rebuilding a new profile
Some extensions reported having Unresponsive Script Errors
Websites
If you get the Unresponsive Script Warning on a specific web page, it could be a problem with the JavaScript on the web page. You may want to contact the webmaster of the site to inform them of the problem, or you may wish to file a Tech Evangelism bug report. Steffen Rusitschka suggests using setTimeout on web pages that need to execute JavaScript for long periods of time.
Updating Java
Updating Java seems to have helped the following pages. Note Java is not the same as JavaScript.
Webroot Spy Sweeper
The Webroot Spy Sweeper application can cause an Unresponsive Script Warning on certain web pages. Try disabling or uninstalling the application, then clear cookies for the related websites. [18]

Warning Unresponsive Script in Firefox
I have been encountering a warning in Firefox lately which notified me the that a script on the current website was unresponsive asking me if I wanted to stop or continue. That’s a pretty vague warning and I was puzzled at first about the cause of it. The strange thing was that the website seemed to have loaded completely and that the warning was displayed despite of this.
There are two possible causes for the error. It could be caused by a Firefox add-on or by a website which uses faulty JavaScript code. It’s actually pretty easy to discover the cause for the warning message. Users need to stop the script and access the Firefox Error Console using the shortcut Ctrl-Shift-J or with a click on Firefox > Web Developer > Error Console in the menu. The last error message there should hint at the cause of the error.
Generally speaking it is more likely that an extension is the cause if you encounter the error on several different websites while a warning on the same website points to a faulty JavaScript on that website instead. There are exemptions of course, for instance if you run an extension that modifies the behavior on a particular site for instance.
If you suspect that a script just needs a few more seconds to run you need to edit a setting in the Firefox config. Type about:config in the address bar and filter for the string dom.max_script_run_time. The default setting is 20 (seconds), just add a few more, raise it to 25 for instance or even more.
There are a couple of other options available to resolve script warnings in Firefox. You can for instance install an add-on like NoScript or YesScript to either block all or only select scripts from running in the browser. Note that this works well only if the script is not required for the site’s functionality.
Another option to find out if extensions are causing the warning message is to run Firefox with all extensions disabled. You can do so with a click on Firefox > Help > Restart with Add-ons Disabled.
