Firefox shows server not found but other browsers work

kernel_panic · 2011-10-22 06:56:38

Hello All,

I have this weird issue, my firefox shows "server not found" for every webpage. I see "Looking up <URL>" on status bar for fraction of a second and then the error message.
This started after I moved to my friends place and started using his internet connection.

Chromium works fine and all other applications that use this network are working normally. Also I booted into Ubuntu and firefox was running fine on the same network.

So the weird part is firefox is not working only on this particular network (tried both wireless and wired) in archlinux (it works fine on my office network).
And I have no proxy settings.

Could you please help me with this issue ?

Have you tried (re)moving the profile and starting without one?

kernel_panic · 2011-10-22 07:04:03

Actually I did:
$ mv ~/.mozilla ~/.mozilla.bak

and restarted firefox but still the same issue.

It definitely sounds like a profile issue to me. Have you tried to completely uninstall firefox, remove your profile and reinstall and start with no profile whatsoever?

kernel_panic · 2011-10-22 07:12:23

Yes I removed firefox using 'pacman -R' and re-installed.
BTW what do you mean by complete uninstall and profile removal ?

I meant, before reinstalling firefox, purge any settings with:

rm -rf .mozilla*

Yes I had done that and tried everything again now, but still the same error.

The only other suggestion I have is to install another webkit browser (midori is pretty lightweight) to see if it is an issue with something further down the stack...

Otherwise, sorry: that's all I've got

Yup even midori is unable to load web pages.
It shows "Cannot resolve hostname" for all websites.

I am also having this problem. I just installed firefox for the very first time on this current install of arch and immediately did not work.

Found this on the Mozilla site here changing some of these settings might help.

Firefox connection settings

If you connect to the Internet through a proxy server that is having connection problems, you will not be able to load websites. To check your Firefox proxy settings:

At the top of the Firefox window, click on the Edit menu and select Preferences.
Select the Advanced panel.
Select the Network tab.
In the Connection section, click Settings....
Change your proxy settings:
If you don't connect to the Internet through a proxy (or don't know whether you connect through a proxy), select No Proxy.
If you connect to the Internet through a proxy, compare Firefox's settings to another browser's.
Close the Connection Settings window.
Click Close to close the Preferences window.

DNS Prefetching

DNS Prefetching is a technique Firefox uses to speed up loading new websites. To disable DNS Prefetching:

In the Location bar, type about:config and press Enter.
The about:config "This might void your warranty!" warning page may appear. Click I'll be careful, I promise!, to continue to the about:config page.
Right-click in the list of preferences, select New, and then select Boolean.
In the Enter the preference name window, enter network.dns.disablePrefetch and click OK.
Select true when prompted to set the value and click OK.

IPv6

Firefox supports IPv6 by default, which may cause connection problems on certain systems. To disable IPv6 in Firefox:

In the Location bar, type about:config and press Enter.
The about:config "This might void your warranty!" warning page may appear. Click I'll be careful, I promise!, to continue to the about:config page.
In the Filter field, type network.dns.disableIPv6
In the list of preferences, double-click network.dns.disableIPv6 to change its value from false to true.
