Often while browsing or working within Firefox, I have been getting an unresponsive script warning. I would usually let the script run longer but this was not letting the issue be corrected and Firefox would crash. Now there are a two fixes I found for this.
- In the URL, type “about:config” and press the “Enter” key.
- Once on this page, the “This might void your warranty” may appear. Select “I’ll be careful, I promise!“ This will allow you to continue to the about:config page.
- Once in the about:config page, search for “max_script_run_time” and then double click it.
- The default integer is usually “10“, it is recommend to switch it to “20“.
- Then press “OK“.
Now scripts will be able to run for longer times, hopefully you will never see the script unresponsive warning.
If the error only happens on specific webpages you can block the scripts from running. Most site will keep functioning without scripts running.
- You can install YesScript add-on for Firefox, the browser will need to restart.
- Once Firefox is open, click on “Tools” in the menu and select “Add-ons”.
- Once it is open, click on YesScript.
- Click the options selection.
- In the “YesScript Blacklist” dialog, type the URL of the site or sites that are causing you issues.
- Click on “Add”, the domain name of the site or sites will be added to the list.
Now the sites you are having issues with will be blocked from running scripts and should no longer give the unresponsive script warnings.
