How to Find and Fix Unresponsive Script Errors in Browsers

Internet users, if you are frequent receivers of the infamous ‘unresponsive script’ error in web browsers, you are hardly alone. It is the most common error that can crop up anytime, on any browser, be it Chrome, Firefox or Internet Explorer.

The root of the trouble, of course, is a certain piece of JavaScript code present within a page of the website you have accessed, or a browser add-on that refuses to run fast. And, the browser presents you with the options of either stopping the script from running, or of continuing with the same. The former is a safer option because, the latter can drain the browser of memory and even cause crashing.

Now, unless you own the website and run it all by yourself, there’s nothing you can do to fix the problem. But, if the problem persists on different websites, know that there is an issue with the browser add-on or the computer itself. Therefore, you need to find the cause first. But, how?

Start with the Error Console if you own the site.

If you are using Firefox, open the Error Console, which will show you the cause of the problem, if it has occurred within a web page. You can open this console by pressing the Alt key and viewing the File Menu. Choose Tools, go to Web Developers and select Error Console. Take notice of any error in the script that is preventing the execution of the page, or of related pages. Check for nonexistent loops and for data loading from an unavailable sources. Observe if there is a tussle between the script and browser add-on.

Disable add-on in your browser.

If a browser add-on is causing the trouble, disabling it will resolve the issue. To track the problem, disable and enable these applications one by one and check which application responds. You can also run the browser in ‘safe mode’ to see if such an application is causing the glitch. If you are able to run the browser in this mode, be sure that there is not any problem with your add-on.

Alternatively, you can also download error scanners that will help you detect the source of the problem.

How to fix this issue in Firefox:

Find the script run-time value in configurations. Change the default value to 20. If the problem is not resolved, reset the value to default. Installing specific plug-ins and feeding them with the address of the unresponsive website also helps dismissing the problem. Alternatively, disabling hardware acceleration in Firefox also solves the issue. Another option is to stop the browser from synchronizing items like applications, history, passwords, settings and tabs.

How to do it in Chrome:

Just like in Firefox, disabling the synchronization feature works for fixing unresponsive script errors in Chrome, too. Again, the problem may lie in the antivirus you are using. If you have installed Avast, know that this software comes with a browser plug-in like other antivirus programs. But, often, this plug-in stops working, leading to run-time delays, hangs and crashes. Disable this security extension to get rid of the error message.

Fixing the issue in Internet Explorer:

You need to change specific Registry Settings to resolve this issue in Internet Explorer. Also, you can make changes to the Hosts file in which, Internet Protocol addresses and network configurations are present. Alternatively, try clearing the Domain Name System memory with the help of the flush command.

The unresponsive script error is a big headache, and very common, especially in Firefox browsers. But, like the popular saying goes, there is always a solution to every problem. And this hiccup, too, does not go without a gush of fresh air.
