Dummy Essentials: dom.max_script_run

Warning: Unresponsive Script [Firefox]

If we guess right, most of us face this problem at some time or the other while surfing websites in firefox: Warning: Unresponsive Script. 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. [Refer the figure below for the exact error message]

Not to worry :) The solution to this isn't really difficult and we can fix this problem by following these few simple steps as mentioned below:In the Firefox address bar, type about:config and press Enter.

You would probably get a certificate stating: This might void your warranty! You can ignore that message this time and click on the button: I'll be careful, I promise!

The following page would open up:

In the filter box, below the address bar, type: dom.max_script_run_time and press enter. The details of the preference name dom.max_script_run_time would open and the remaining entries vanish, which makes it easy to work through.

Double-click on that entry and change the default value which is given as 10, to something higher. I changed mine to 1000. You can also comfortably change it to that or experiment with something that suits your requirements.
