I'm trying to access using Firefox from my Archlinux system and I get the following error:

Firefox can't find the server at

When I use Chromium, it works perfectly.

I tried deleting the ~/.mozilla directory, with no success. I've also tried running Firefox from another user session, with no luck.

I'm running the latest version of Firefox.

Any ideas?

What does host return from your machine? Does Chromium have a proxy configured? –  EightBitTony May 21 '12 at 21:56
What are your proxy settings in Chrome and Firefox? What is your DNS configuration (if you don't know, start by posting the content of /etc/resolv.conf)? –  Gilles May 21 '12 at 23:11
host has address Host not found: 3(NXDOMAIN) –  Ben D May 22 '12 at 9:36

I have the same problem on a fresh Archlinux installation.

My resolv.conf contains only


(plus a few comments) It's the address of my "box" (router, modem...). It works perfectly for every other domain (Belgacom is my ISP).

I tried a ping but it fails. I installed Chromium to test and it's working but it's not working with Epiphany, so I guess it's not a problem with Firefox. Other computers (on Ubuntu) using the same address as nameserver can access to this domain.

A dig gives me this result :

I fixed this problem by adding 2 old dns servers to /etc/resolv.conf :

If it works on the same machine under a different browser check if you have proxies enabled or if any of the installed addons is interfering with DNS resolution.

Since you already removed your profile folder and even tried different user sessions, my bet goes to preinstalled addons or proxies.

Close any firefox instance and try firefox -safe-mode. If this doesn't work, check that you don't have any proxy enabled.

If neither works, I've no idea what could be wrong.

I tried running firefox in safe mode with no success. I don't have any proxy –  Ben D May 21 '12 at 17:29
Just out of curiosity, that address wouldn't happen to be the place where you work? I'm wondering if you have something on your /etc/hosts file or in the network that makes the address resolve locally instead of via the external address... –  Unode May 21 '12 at 19:43
No, I'm trying to access it from home. –  Ben D May 22 '12 at 9:29
