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.

*** Bug 62616 has been marked as a duplicate of this bug. ***

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.
