Why am I still getting hang ups...

[Waseem]

Hello,

I am still getting hang ups, and long and debilitating, hang ups even though I have No Script installed and activated.

Every so often I get this slow down of my machine, Windows XP Pro, Pentium III with 1GB RAM, and about 3/4 of the hard drive empty, using FireFox 10.0.2, and then a message comes up:

The title of the message is: Warning:Unresponsive script.
The body of the message is: 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: resource://gre/modules/XPCOMUtils.jsm:331

The message have a Don't ask me again checkbox, and a Continue and a Stop script buttons.

Why is this happening when I have No Script running?

Thanks

Waseem

What is the address(es), or URL(s), where this occurs?

Could you please open Firefox Tools > Web Developer > Error Console, click "Errors", and copy any red Error messages and paste them here? Also please click "Messages", and post here any messages relating to NoScript.

The unresponsive script if from Firefox's internals, and thus cannot be blocked by NoScript without breaking the browser.
Most likely what you're seeing it's a misbehaving extension. Could you try Standard Diagnostic?

FWIW, Giorgio, I have encountered this on rare occasions even on Yahoo Mail. They run as many as 120+ scripts at times, and that is *only* from mail.yahoo, not www.yahoo, which is disallowed.
I just figure that they crashed into each other, or overloaded something, and usually, "Stop script" lets everything continue normally. Perhaps if the script is necessary, once it's stopped, it starts again, this time with less competition from the others? -- could you enlighten me as to why this fixes the issue? Could be an easy fix for OP, if it works.

I have only six extensions. AFAIK, none of them are known to cause conflicts as ABP and Ghostery often do.

By "this", do you mean an unresponsive script from a "resource:" or a "chrome:" URI (i.e. from Firefox's internals), or instead from a *.yahoo.com domain (which would just mean that a script in content is too slow or stuck in an endless loop)?

I've never seen that type of detailed warning with script name, and since "Stop script" works, never bothered to look in Error Console.
If it happens again, I'll investigate further, but I suspect that you are correct about the *.yahoo running slowly or looping.

IIUC, you're saying that a message as detailed as OP's must be from Firefox's internals (only from resource or Chrome), and would show up onscreen in that fashion? No, I've never encountered that. Sorry for muddying the water.
