The main reason why this problem appears is that the browser on some website can’t run JavaScript. The script prevents Firefox to continue with work which stops the browser automatically, thus, you’ll see firefox unresponsive script error. If you want to prevent this issue, just follow these instructions:

  • Open Mozilla Firefox browser.
  • In the address bar at the top of the window, type “about: config” and press Enter key.
  • Then you will see a warning message that says: “This might void your warranty”. Click on the button “I’ll be careful, I promise”.
  • You will see many options on the list, and you have to find the desired settings using a search box.
  • In the search box type: “dom.max_script_run_time” and press Enter.
  • Then, double click on the search on the preference name and the new window will open. There you need to enter number 30 and press “OK” button.

  • Restart Mozilla Firefox and you will not see this error in the future.

 

You can also use an add-on known as “YesScript” to fix Unresponsive Warning on Firefox.

In the search field type “YesScript” and click on “Install” button next to the add-on.

  1. Please, I need help on how to permanently get rid of the “Unresponsive script” warning. I have tried this “dom.max_script_run_time” set to “30” but it does not work I keep getting this warning when I surf the net. I am at my last straw here, I am considering moving to google chrome. I understand this is supposed to help keep the browser from running slow by turning off the script but this is far more annoying. Everything is fully up to date but I am starting to put off my hair. I would like the option to hide or turn off this.

  2. Simply, upgrade RAM. It will solve it. Mine, from 4 to 12 GB.
    I’ve encountered this unresponsive script, looked around for solutions but to no avail. Thus, I’ve upgraded RAM from 4 to 12GB and enjoyed the benefits of faster programs start up and last but not least, no more unresponsive script error.
    The above gives your laptop/PC more RAM and time to process things thus no more such nonsense.
    My previous laptop 4GB RAM config:
    – Win 10, 4 GB RAM, 1TB Disk space, ran, Chrome, Firefox, Thunderbird, Word, PowerPoint, Excel, Screenshot. These are daily word processing stuff isn’t it. For this, each time my lappy woke up from screensaver, script error is a sure encounter.
    Upgraded RAM config, no more script error nonsense. All programs opened quickly and I switch between the above programs constantly.

  4. about:config -> dom.max_script_run_time set value to zero
    dom.max_chrome_script_run_time set value to zero
    Restart FireFox.
    Done!

  5. i done all the same b.s .. and it’s STILL and issue… and it’s weird as it does not happen on my cell phone . it’s only on my laptop and pc at home….. strange that no one has a fix for it…… and YES i’ve checked everything / upgraded and all that good stuff… still issue’s .. …

  6. Your How To Get Rid Of Warning Unresponsive Script In Mozilla did not work for me.
    At first I did what firefox suggested in applying that “Yes Script” thing and it didn’t work because face won’t work at all using that.
    Then I one by one disabled my add on’s to see if any of them were causing the script message to appear that disabled my facebook page.
    Nothing worked, it still popped up. So I tried this page to do the “about: config” and then the “dom.max_script_run_time”, and then to input the number 30, and it didn’t work either.

    I’m running windows xp with the firefox browser, last year use to have the google chrome, but they stopped supporting windows xp so I went with firefox, and now you too are going to stop supporting windows xp in august, so I might be going offline all together, because I really can’t afford a new computer.

    So here we are, technology screwing my livelihood.

    When I first started using firefox I don’t remember that script message popping up.

    So what else ya got, or is this one of those problems that no one can solve, it’s just there, like bad political leaders mandates, Ha!

    1. Same here. A perfectly functioning XP Pro machine rendered obsolete before it’s time. What I did was download, install, and learn Linux. Certain programs that only run on Windows can be run in Linux using “Wine”. Good luck.
