"Warning: Unresponsive script" message and Firefox v16+

I recently upgraded to v16, and then v17. In both cases I repeatedly received the dreaded "Warning: Unresponsive script" message, so frequently that the browser became unusable.
https://support.mozilla.org/en-US/kb/warning-unresponsive-script
I reverted to v15 and now I NEVER get the "Warning: Unresponsive script" message anymore
Just so you know...

Error message: "Warning: unresponsive script". Afterward, the system freezes and will then crash. Crash reports have been submitted many, many times without response. I have tried the fore-mentioned solutions with either no results or very bad results which I filed a report but did not receive an answer. The application to block scripts actually worsened the problem and I could not correct the situation for a while (no response from Firefox, at all). I have also been through this procedure without any one contacting me, AT ALL.
== URL of affected sites ==
http://http://www.facebook.com (always) and www.YouTube.com (sometimes)

There does appear to be any support whatsoever from mighty "non caring" FIREFOX & people are getting fed up. We may as well try another system, if they can't be bothered to provide any support for their system, we can't be bothered to use their system.

Firefox was fast when I first started using. Now, very slow to open and freezes often. Frequent message is "Warning-unresponsive script". Do I need to switch back to Internet Explorer?

Switched from Internet Explorer because seemed slow. Firefox was fast at first. Then upgraded to Firefox 4 and frequently have trouble opening. Sometimes page doesn't open, or is very slow. If I try to open again I will get Mozilla Firefox Unresponsive or a message that say "Warning-Unresponsive Script". Often have to restart and do the whole thing again. Don't really want to switch back to Internet Explorer, but getting tired of taking a half hour to get into my emails!

I am having the same problem, but not sure what's causing the slow down. Restarting in safe mode fixes the performance problem... but disabling all plug ins and extensions in normal mode (and restarting firefox) still shows the bug. Any ideas?

Whenever I try to open Mozilla a pop-up box appears stating: "Warning: Unresponsive script."

When I log onto Mozilla, a pop-up box appears stating the following:
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.
I have tried clicking onto both "stop script" and "continue," but either choice doesn't resolve the problem.

Start Firefox in [[Safe Mode]] to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
*Don't make any changes on the Safe mode start window.

Unresponsive Script message when sending messages on Angel Learning software.

I get the following error message when trying to send messages on Angel Learning software using the Firefox 7.0.1 on my Macbook pro (OS X)
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.
Script: http://angel03.gcu.edu/jscript/yahoo/utilities/utilities.js:9
Can I download an older version of Firefox? As far as I know, Firefox is the only browser that is suppose to work with all the features of Angel. Now it appears that it doesn't work with the message feature.

Firefox came up with the unresponsive script message and now if frozen?

Firefox came up with the unresponsive script message. I clicked 'stop script' but now Firefox has frozen and is not responding to anything I do. I cannot click on anything. It will not let me close it down, uninstall it or shut down my computer.

Upgraded to FF 33 and installed English dictionary. Now FF is hanging frequently in www.morningstar.com and I believe elsewhere with the following:
Warning: Unresponsive Script
Script: chrome://browser/content/browser.js.17006
I do NOT understand the "chrome" reference.
This is quite annoying. I upgraded to FF 33 in order to try to get back spell checking in Morningstar posts which I lost back at FF 24, as I recall, but it did NOT solve the problem. Now I have this mess.

Why i get this "Unresponsive script" message

Another problem with the Firefox browser which shows the following message. " 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.
The following message, causing Firefox to be stuck and freezes, as is evident in the tab bar of Firefox.
And I try to close some of the tab bar but is still unable to respond which means that I have to wait to be able to browse again.

This sort of message can have many causes, and is often due to a problem site or problem add-on.
* do you only get the message on specific sites, or when doing certain tasks ?
*What is the actual message, is it the same each time ?
* to see if the problem relates to additional software try Firefox in safe mode
** see [[Troubleshoot Firefox issues using Safe Mode]] on XP use Help -> restart with add-ons disabled do not make changes in the first window with check box options, just click on continue.

Unresponsive Script Message

I keep getting a message in various browsers "Warning: Unresponsive Script" and the choice of "continue" or "stop script. What is causing this and how do I correct it to keep if from happening?
Thank you.

You can try the following... it worked for me.
• In address bar type: about:config
• In search field enter: dom.maxscript_runtime (or scroll down)
• Double-click that entry and change the value - (the default is 10)
Most sites recommend 20, thats what I tried. & worked @ facebook.
the cause being JavaScript. Also you may want to give YesScript
extension a try.

Unresponsive script message, "Script: chrome://somoto/content/tb.js:2977", continue or stop script

On opening firefox (which now seems to take longer than previously, an error dialogue opens headed, "Warning unresponsive script" followed by the message,
"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.
Script: chrome://somoto/content/tb.js:2977
I am then invited to check the tick box if I don't want to be asked again (of which no notice is taken)
I am also invited to "Continue" or "stop the script".
This occurs every time I open FireFox, and on opening, for example, a calendar where I must select a date in order to proceed with my Medicare provider claim.
In summary, two problems: slow to start up; and the persistent error message.
Thank you for your help!

That type of message is usually due to a incompatible/malforming add-on. Try the procedure in the [[troubleshooting extensions and themes]]. First look for any that contain somoto in their name or initials.

Got Unresponsive script message. Whether I click on Stop script or Continue, it doesn't respond and browser has freezer. Can't even restart my iMac.

I clicked on a link and immediately got "Warning: Unresponsive script." Clicking Stop Script or Continue does not make a difference. It just froze or got hung.
I just got your email asking me to confirm the account I created with the username marlener by clicking on the link provided on the email. I clicked on it but it's not going anywhere because my Mozilla browser has frozen. Like I said, I can't even close it. I attempted to restart my iMac but it won't because it says I have to close Mozilla first.
I often get the Unresponsive script warning now that I've switched to iMac. I don't remember getting this msg too often on my Windows desktop. Is Mozilla more incompatible with iMac compared to Windows?
The screen has now turned white but the box with the warning msg is still up and I still am unable to close the browser.
The menu at the top doesn't show so there is no Help window for me to open.

Firefox may become very slow to respond because of badly coded JavaScript causing infinite loops on certain websites [28]. This problem can usually be cleared by closing the window or tab for that website. You can also temporarily disable JavaScript to view the problem site, but the website may not work without JavaScript. Read Firefox CPU usage for more information and also see the related article,Unresponsive Script Warning.
If the web site hangs Firefox (you can't even exit Firefox) try running in Safe Mode and see if you can get an Unresponsive Script Warning. Watch the status bar and see if this frequently occurs while it mentions a specific URL. If so, try blocking that URL using a content-blocker such as Adblock Plus. The problem URL may be fetching an advertisement or side panel that you can do without.
If none of this helps, try using a different browser (such as IE or Opera) or try accessing the site at another time. This might help you determine if the problem lies with Firefox, a poorly designed website, or content that changes over time, such as ads.

I have pretty much the same problem -- I run three different types of Browsers (Firefox 3.6; Internet Explorer 6; Chrome) and I've found that they are all affected by this ... thing.
I suspect that there is some kind of war going on, or a very aggressive move by Yahoo onto the Browsers and Search Engine scene. With Yahoo trying to be an 800 lb (Pound weight) Gorilla - again, Yawn!
I this because I've recently installed an AntiVirus application (which is a really good one -- but, unfortunately for the AntiVirus maker they did not look closely enough at who they were getting into bed with -- The 800 Pound Gorilla, Yahoo.
This AntiVirus's installer had a default setting to make Yahoo Search my default search engine -- it was a tiny notice about this and I happened to look otherwise Yahoo would have installed openly onto my computer (and I don't want them. I've been using computers since before the Internet was publicly and generally available and I know only too well Yahoo's Huge Ego and Navel gazing behaviour.
Basically, Mozilla are on Yahoo's side, because -- in the minds of the anarchists of Mozilla -- Google had no right to make a Browser.
This is Mozilla getting its own back on Google and Google Chrome. Mozilla are culpable in this assault on our own property -- our own computers. By two organizations who are bitter at Google. Actually, they are jealous of Google because Google succeeded on the quality and purity of Google products and their terrific business sense and strategy.
Now, Mozilla and Yahoo have got in cahoots (and chumps like the supplier of my AntiVirus have been sucked into this) to "Do something about Google" as Mozilla proclaimed they would do (should they get the chance) some few years ago.
Now, I have in my computer: Yahoo software and a Mozilla Browser which are both acting truly as Malware. Now that AntiVirus company which loaded Yahoo software onto my computer can understand why I wrote to them pointing all this out (and they, a multi-million or billion pound organization missed what tiny little me could see) that they have helped Malware get onto my system -- now their up-to-that-moment very well thought of AntiVirus and organization ... Well, their name is now mud (but I shall not say their name here. Let them suffer their stupidity and shame, that should be enough for them. They are going to have a time of it cleaning this little ol' mess up.)

Warning: unresponsive script error

Cant get rid of the Warning: unresponsive script error. HELP!!!

We need more information - does this only happen on a specific site, or all sites?

Warning unresponsive script came up but won't let me stop the script or continue it or anything. help!

I'm on a MacBook air. I tried to close Firefox and it won't let me, I tried uninstalling it and won't let me, and I tried shutting down my computer and still won't let me do anything! Someone please help me! I already called Apple and they said they couldn't help me because Firefox isn't part of them. Also Firefox really needs to get a customer service number!

Hi OliviaMancia,
I understand that you have an installation of Firefox that is giving you the unresponsive script warning. I also understand that you filed this for Firefox for Android as well as Desktop?
None the less, please see [[Warning Unresponsive script - What it means and how to fix it]] for Desktop. As for the mobile version please try the add on Noscript or Adblock Plus to block some unwanted scripts.
Unfortunately Mozilla currently does not have the resources to maintain a Support line.

Warning: Unresponsive script' message appears in 'do forever' loop.
