215976 - show error pages instead of JS alerts for http errors (ala IE or Konq)

Status: VERIFIED DUPLICATE of bug 28586

(Core :: Networking, enhancement)

Description

[Robert Mohr]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.5b) Gecko/20030801
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.5b) Gecko/20030801

It would be nice if the JavaScript alert() function could be added to the list
of things that can be disabled in Preferences | Advanced | Scripts & Plugins. 
Either completely removing it (possibly bad), or having it show the text in the
browser window instead of in an alert window.

Reproducible: Always

Not likely to happen any time soon, if ever, depending on the demand for this...

The basis behind me wanting this bug was that if Mozilla fails at making an HTTP
connection, it pops up an alert saying so, taking away focus from whatever you
are doing.  Then you must dismiss the alert, and click refresh to make the page
reload.
