 How to Fix “Warning:Unresponsive Script“ in Firefox [Updated]Update: This is worth the try.

Install YesScript extension which lets you block JavaScript that is causing problem on specific websites.

Install the add-on, restart the browser, open its options and add the page/site on which warning is appearing to block that script.

Let me know this is working for you or not through comments.

Recently, while I was browsing certain websites and reading mails in Gmail, got unresponsive script warning in Firefox, it caused Firefox to hang and give that warning message.

Why this warning comes in Firefox ?

This warning comes due to several reasons as Firefox unable to handle java script on that website you are browsing, and may cause Firefox to hang that’s why Firefox asks to either to stop the script or continue the script on that page.

But neither stopping the script, nor continuing the script does not yielded any favor, I got the same warning again while browsing those sites.

What could be the reasons that caused Firefox to give this warning ?

The reasons could be due to Add-ons installed in Firefox or the java script in webpage you are accessing or Firefox it self.

Since this Script warning comes to me when browsing Gmail and couple of websites, I suspected Firefox, since the Firefox version using is outdated and also Firefox stopped the support to Firefox 2.0 (Only one computer in network is using Firefox 2.0 and remaining are updated one’s).

What’s the Fix?

So I updated the Firefox 2.0 to latest version of Firefox that is Firefox 3.07, ,after that I have no warning problems in browsing Gmail and couple of Websites I mentioned above. This could be different in your case if you get this unresponsive script warning, but the ultimate fix to this I recommend is updating to latest version of Firefox which fixes these warnings and bugs.

Letting the script run longer

If you find that pressing the Continue button brings up the same dialog again, letting the script run longer won’t help you; it will just make Firefox hang for longer. However, if you can use Firefox normally after pressing Continue, then the script may just needs extra time to complete.

To tell Firefox to let the script run longer:

In the Location bar, type about:config and press Enter.
The about:config “This might void your warranty!” warning page may appear. Click I’ll be careful, I promise!, to continue to the about:config page.
In the about:config page, search for the preference dom.max_script_run_time, and double-click on it.
In the Enter integer value prompt, type 20.
Press OK.

this problem drove me nuts!!! i did everything i could think of to fix it and nothing worked: upgrade browser, run virus scans, pc tuneup software, check for spyware, read mozilla’s fix, etc. eventually, i got fed up and disabled mozilla’s crappy Java reader.

ctrl + shift + A will open mozilla’s add-on manager. click on PLUGINS located on the left of the screen. disable Java(TM) Platform. disable Java Deploy Toolkit.

hope this helps

I tried the about:config solution and it didn’t work. I also tried several things on various boards but nothing… Firefox still hung. Talk about annoying. I finally decided to ditch Firefox and switch to Opera just to stop the script problem.

Well, that didn’t work either. Opera was giving me the same problem. That got me to wondering whether it might actually be something in the operating system. I went to the following page…

http://www.vistax64.com/network-sharing/221486-help-stop-running-script-msg.html

and downloaded the ActiveX updater. Surprise! That worked for me. I’m guessing that it will work for many of you too. And, there’s also a Runtime updater on the page that can be downloaded (although I didn’t need to).

Hope this helps…

The thread discussion about stopping IE script errors here its Firefox so what you said or thread addresses no way related to this post.

I have Mozilla 10.0.1 and I still get the Unresponsive Script warning.

I get the same crap on FF 10.0.1

I’m getting a little tired of Firefox to be honest. It’s almost as crap-tastic as Internet Exploder.

I was having this problem but only on my blog, it was a widget I had installed, invisible on the blog, but still there doing ‘something’ on the back end. I deleted it, no problem. So perhaps it may be nothing to do with Firefox…

That’s on your end, but there is something relate to Firefox it could be add-ons or other things still yet not sorted out. Anyway glad to know that there is no problem for you.
