Unresponsive Script- A Script On This Page May be Busy,It May Have Stopped Responding

For the past few days,  I have been getting an error message on Firefox while browsing. The error message is 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. There are two buttons on the error message, continue and stop script. If we press the continue button, Firefox starts to wait for the completion of the process.

If you are not patient, you can stop the code by pressing the second button. Reason for getting "Unresponsive Script" error message is the long time taken by it to execute than the expected time set in the Firefox configuration.

If you are not familiar with the error, have a look at the screenshot given below. As I explained before, if we do not press the "Stop Script" button, this message will stay a very long time. We have provided the Solution to this Firefox Unresponsive Script error below.

Firefox Unresponsive Script Error Solution

To solve the unresponsive process error, we should increase the maximum time Firefox wait to declare a code unresponsive. It is because sometimes Mozilla decides a particular program is not responding before completing its process due to the lower time set to decide whether a process is working or not.

To do this follow the steps below.
  1. Start Firefox

  2. Type about:config on the Address bar and press enter

  3. Click on I'll be careful, I promise!

  4. Double click on dom.max_script_run_time
    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.

  5. Enter the maximum  runtime 25 and click OK
By increasing the maximum runtime, we can avoid most unresponsive code error messages. Each process will get enough time to start work normally before generating an alert to stop it.  Just like this, if you are looking for different methods to clear cookies, follow the link below.
