45131 - [RFE] DNS lookup error notices should be able to be disabled

Status: VERIFIED DUPLICATE of bug 43266

(Core :: Networking, enhancement, P3)

Description

[Jason Keirstead]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Win98; en-US; m17) Gecko/20000710
BuildID:    20000710

I
use a fake entry in my local nameserver to point *.doubleclick.net to a non
existant IP (to avoid banner ads). Whenever I go to a site that has a
ad*.doubleclick.net ad, mozilla echo's 3 or 4 warnings to me saying that the
host could not be resolved. I realise that this is a good thing to have, but I
wish it could be disabled in advanced options somehow, it is VERY annoying.

Reproducible:
Always
Steps to Reproduce:
1. Impliment a local DNS, with doubleclick.net pointing to a nonexistant host, and
don't put in any sub-hosts
2.Go to a web page that has a doubleclick ad
3.

Actual Results:  Echos
several times "ad*.doubleclick.net cannot be resolved"

Expected Results:  You should be able
to disable this warning

gordon: who throws these warnings? if its the webshell then this should go to 
rpotts. I use the same mechanism and it can be annoying.

I use a local webserver and direct burstnet, etc. to 127.0.0.1 to get around 
similar problems.

Fixing bug 28586 (or bug 33469) is probably the best way to fix this problem 
from the Mozilla side.

Adding [RFE] to summary.

A few points:

1) This is not "trivial", as the bug is marked now. It is _very_ annoying and
makes me use Mozilla less. Most "high profile" web pages have a number of ads
that are blocked. Having to click (no, keyboard doesn't work) several popup
dialogs for every single web page viewed is simply too frustrating to stand.

2) The bug can be reproduced for Linux (and, I guess, all other unices) by
simply adding an entry in /etc/hosts:

127.0.0.1
ad.doubleclick.net

But then the error message is "connection refused" (unless you run a local
webserver.)

3) I would be happy with a preferences.js setting if that's easier to start with.

By the way, bug 43266 (one of the dups of bug 28586) is the same as this bug.

Verified dupe of bug 43266: "Rethink dialog usage" which is a 
dupe of bug 28586: "[RFE] Should use error page, not dialog, for inaccessible 
pages (placeholder)"

[RFE] is deprecated in favor of severity: enhancement.  They have the same meaning.
