Checking the 'prevent this page from creating additional dialogs' box stops executing javascript on the next 'alert' statement

more options

Hi,

I'm currently working on a javascript script. For debugging purposes I have it display lots of alerts so I can see what it's doing.

However, when I check the 'prevent this page from creating additional dialogs' box on one of the alerts, Firefox then stops executing the javascript on the next 'alert' statement in the script.

---

I get this error in Firebug:

Component returned failure code: 0x80040111 (NS_ERROR_NOT_AVAILABLE) [nsIDOMWindow.alert] [Break On This Error]

alert(responseData);

---

If I do not check the 'prevent this page from creating additional dialogs' box, the script works fine.

If I disable the Firebug extension the problem persists, so it cannot be a Firebug problem.

Is this a bug in Firefox? I'd appreciate any help.

Someone may reply, but you may have more success asking elsewhere, maybe on a mozillazine forum.

Try posting at the Web Development / Standards Evangelism forum at MozillaZine. The helpers over there are more knowledgeable about web page development issues with Firefox.
