A script is anything on a web page which you are trying to access, or in an extension that you have installed.

You must have received a warning message as “Warning: Unresponsive script.” The browser stops loading the page you were surfing. It may happen when a fragment of the Javascript code takes too long to run. The screen flashes ”A script on this page may be busy or may have stopped responding.” You are left with two options “Stop Script” or “Continue.” Click on the Stop Script button.

This error is an indication that Firefox has read a script to run out of control and this would hang Firefox sooner.

If the problem occurs only on one particular page, then it’s likely that a script on that page is causing the Firefox Script Error. Whereas, if you face such an obstruction on other websites as well, then there is some issue with your device or a browser add-on is responsible for the same.

As you can see it is essential to find out what is causing the error. To identify the underlying cause, try the following procedures-

1. Open the Browser Error Console


To open the console, Press Alt for the File Menu to show up. Select Tools>Web Developer>Browser Console. As an alternative, you can also press the Ctrl+Shift+J tabs.

You have to look for references for a specific script that is generating the crash message. Once you find the one, click on disable. This process may not be easy for the ones who are not tech savvy. Therefore in most cases, it is observed that users search for professional help.

2. Disable Add-ons

There is another way to detect the faulty script. Access the browser in the Safe Mode. Keep disabling individual add-ons to find out the actual one that was causing the error. Also if you open Firefox in the Safe Mode, you may get rid of the issue. If there is no problem in the Safe Mode, then the add-ons are to be blamed.

3. Clicking The “ Continue” Button

When you are confronted with the options of either choosing Stop Script or Continue, click on Continue. To continue using Firefox normally if you have to instruct Firefox to let the script for some time. Follow the steps-

  • Type “about: config” in the address bar and click on Enter.
  • Select the “I accept the risk!” to continue.
  • Type “dom.max_script_run_time” in the “about:config” page.
  • Type “20” in the Enter integer value and press OK

Scripts will be allowed to run long and you will receive the Firefox Script Error.

If the prompt comes back, then you have to set the preference back to its default value. Type “about:config” in the address bar and click on Enter. Select the “I accept the risk!” to continue.

Type “dom.max_script_run_time” in the “about:config” page. Right click to get to the Reset option. Click on it and the changes will get reset to the initial setting.
