How do I see full page error messages from Firefox?

In IE, I get a verbose error - In Firefox, I get a small java alert.

Basically, I code ASP applications and when I used IE all I needed to do was to enable the Java Console.

What happens when a page errors out is that I get a full error page displayed - most often with the type of error listed, and a line # at which it occurred.

In Firefox, I get a small java alert that pops up and says the page just ain't gonna load.

Is there a way to enable the same type of verbose error page as IE displays - but in Firefox?

Firefox has an error console too(better than IE's). In the "Tools" menu.

Yeah, but I think this has less to do with the Javascript Console than it does on how the browser chooses to display error pages.

How can I enable verbose error pages?

Like, so instead of ---

[Alert Box Pop-Up]
***
The connection to www.yourdomain.com has been terminated unexpectedly. Some data may have been transferred.
***

I get an error like this ---

***
The page cannot be displayed

Cannot find server or DNS Error
Internet Explorer
***

Try entering about:config in the address bar - go down to:

browser.xul.error_pages.enabled

change it to true.

Or if your really lazy you can download this extension [extensionroom.mozdev.org]. AFAIK it just makes the change in about:config for you.

Actually... it also shows the troubled location (like if you were redirecting to an unresolvable page) in the URL field as well - so it's worth the 2 second DL.

Thanks for the help.
