Firefox won't browse

Simon Bridge · 05-16-2005, 01:17 AM

Asking Mozilla about a failure to connect with Firefox yeilds (amongst others) the following: http://forums.mozillazine.org/viewtopic.php?t=258042

It basically says that if the firewall is not at fault, then the DNS server (your ISP) probably is. It goes on to show you how to use different nameservers or set up your own with bind.

I have the same problem here. I eliminated the router from the equation since I have another computer with Mandriva RC2 connected to the internet and everything works fine.

But on the box with Mandriva LE, no luck. I can ping, Konqueror works perfectly but no other apps can reach the internet (gecko based browser, bittorrent and so on). Interesting to note that I can have the router configuration page through any browser.

When I do "route", the working box gives me :

Destination Passerelle Genmask Indic Metric Ref Use Iface
192.168.1.0 * 255.255.255.0 U 10 0 0 eth1
default mygate.ar7 0.0.0.0 UG 10 0 0 eth1

The malfunctionning one gives :

Destination Passerelle Genmask Indic Metric Ref Use Iface
192.168.1.0 * 255.255.255.0 U 10 0 0 eth0
127.0.0.0 * 255.0.0.0 U 0 0 0 lo

Uninstalling and reinstalling Firefox is rarely the fix for any problems Firefox might be having.
If the problem is with Firefox, try running Firefox in Safe Mode
If all is well, you have a "bad" theme or extension/s that needs updating, replacement or removal.
Tool>Extensions>Right click to disable or uninstall Tool>Themes>uninstall
If the problem still exists it could be a bad profile in which case you need to Create a new profile.
You can "restore" most of the information from your old profile to your new one.

Try turning off the IPv6.
( This has helped a few people while others said it had no affect or made things worse.)
type about:config in the Navbar/address bar and hit Enter then look for
network.dns.disableIPv6 - right-click and toggle to true
Restart Firefox

Turning off ipv6 did work. I can now use galeon or firefox to go on the net.

I now have just to figure out how to do it for the rest of the distrib (among other things, this problem is interfering with urpmi).

Simon Bridge · 05-22-2005, 09:26 PM

In my distro - I edit "modprobe.conf" and append the following:

#Turn off IPv6
alias net-pf-10 off
alias ipv6 off

That stops IPv6 support at the source. So it should remove ti for everything on your computer. Other distros will have their equivalent.

In my case the problem was that Firefox, for whatever reason, was not getting to my ISP's nameserver. I did the following to fix it:

I found the following link that mentions how sometimes Firefox can have a difficult time getting to your ISP's name server (it also has several very good troubleshooting steps):
http://forums.mozillazine.org/viewtopic.php?t=258042

I went to the following website:
http://www.broadbandreports.com/faq/7472

I chose NS1.QUASAR.NET. I then typed in the corresponding IP address in my /etc/resolv.conf file as follows:

Code:

nameserver 199.166.31.3

Now everything works fine. I modified my /etc/conf.d/net file and added the following to prevent my manually configured nameserver from being overwritten by my ISP:

Code:

dhcpcd_eth0="-R"

I hope this helps anyone who is having wierd Firefox connection problems or wierd hostname resolution issues in general.

Glad to be of service (see post #16 this thread.) <smug mode>

gninnib · 10-25-2005, 10:27 AM

I too am having this exact same problem. I started with Suse 10 and could not get it working with Firefox. I then reinstalled Suse 9.2 and had the exact same issues. I've switched the out the NIC cards and same issue. I know my Actiontech DSL router is working because it works fine with another windows machine connected to it.

If anyone can help with this is would be GREATLY appreciated. Thanks...

Had the same problem as originally discribed in this post - Konqueror would browse sites, but Firefox wouldn't. Also, neither GAIM or yum could access the internet (and I'm sure many other programs but I never checked).

Managed to fix firefox by setting - 'network.dns.disableIPv6' to 'True' in about:config, but other programs like yum still didn't work.

Totally disabled IPv6 in Fedora as per Simon's earlier post.

Result - everything now works!

Thanks very much everyone, if yours still doesn't work after this then good luck getting it sorted.

NOTE: For my distribution (Kubuntu) I had to alter a script that generates these entries on startup and force it to also add my ISP's namesevers. Sorry, but I can't seem to remember where it is now (which is bad if I every do a reinstall).

I am going to install Kubuntu on another computer on this LAN. Expecting to run into this problem again, I hunted down the script that re-generates my /etc/resolv.conf file on boot. The script that generates it is '/etc/dhcp3/dhclient-script'. In this script there is the following function:

Code:

make_resolv_conf() {
    if [ -n "$new_domain_name" -o -n "$new_domain_name_servers" ]; then
        local new_resolv_conf=/etc/resolv.conf.dhclient-new
        rm -f $new_resolv_conf

        if [ -n "$new_domain_name" ]; then
            echo search $new_domain_name >> $new_resolv_conf
        else # keep 'old' search/domain scope
            egrep -i '^ *[:space:]*(search|domain)' /etc/resolv.conf >> \
                  $new_resolv_conf
        fi

        if [ -n "$new_domain_name_servers" ]; then
            # manually set isps nameservers
            echo nameserver MY.ISP.NAME.SERVER1 >>$new_resolv_conf
            echo nameserver MY.ISP.NAME.SERVER2 >>$new_resolv_conf

            for nameserver in $new_domain_name_servers; do
                echo nameserver $nameserver >>$new_resolv_conf
            done
        else # keep 'old' nameservers
            egrep -i '^ *[:space:]*nameserver' /etc/resolv.conf >> \
                  $new_resolv_conf
        fi


        chown --reference=/etc/resolv.conf $new_resolv_conf
        chmod --reference=/etc/resolv.conf $new_resolv_conf
        mv $new_resolv_conf /etc/resolv.conf
    fi
}

I just added the two lines below the "manually set isps nameservers" comment (which I also added). After that, I've had no connectivity issues.

I had the same problem in Suse 10, Konqueror worked, all
the other browsers were too slow to connect to any site.
I could solve it by turning off IPv6 but the solution I
found in the end was to upgrade the software on my Dlink
wireless router to the latest version. In other cases it
seems to be solved by adding the Ip addresses of your ISPs
name servers to the resolv.conf file.

simoneroper · 01-03-2006, 01:27 PM

Hiya. Yay, fellow sufferers. I have this same problem. Hopefully you have some clues as to what is going on, since I see it has been a while since anyone responded to this thread.
I installed Suse 10 onto a brand spanking newly built machine. I am a newbie, so perhaps that was a little ambitious from the get-go. Anyway, I could not get onto the net, no matter what i tried. I had installed the gnome desktop (choice of kde or gnome, and the book recommended gnome). The firefox is the default browser with gnome, so when i could not connect, I assumed that it was a connection issue. I dug around my hardware, messed about blindly with commands, having no idea how to even tackle the problem
To shorten this , I later decided to reinstall and include more features of the installation options, and on a whim, elected kde instead of gnome. Kde's default browser is konqueror, and I got onto the net, no problem. It never occured to me that it might be a browser issue, not a router/NIC issue, until i tried firefox and mozilla and could not get onto the net. I once, like the original poster of this thread got onto novell site briefly, but basically, firefox and mozilla don't work.

Will try what has been posted here, but may battle a bit, not yet comfortable with command lines etc. Glad you all put the info here though, thanks

simoneroper · 01-04-2006, 08:41 AM

Just to let you know that I have sorted out my firefox browser issue, following post 18, by craigevil on this thread. Dead easy even for a complete newbie like myself. My automatic updates don't hook up to the net yet, but will sort that out. At least I am making progress. Baby steps............

shag · 01-10-2006, 12:51 AM

I had the exact problem of Konqueror being the only browser to work, as well as never being able to do a net install with Debian.
Somehow I was lucky enough to stumble upon a thread about a slightly different issue and the solution was to use
the DNS of your ISP and not the router.
Because I always used DHCP, I was always given the default DNS, which is the same as the Default Gateway.
Anyway, once I started putting in my network info in manually and used the ISP's DNS, I was laughin.
Everything worked like a friggin beauty and I only needed to install what I wanted from the net disc,
it was the best.
Now I see people asking this type of question all the time,
obviously it is a very common problem and the solution should be put somewhere easy to
find, so numnuts like me don't spend ages wondering what the friggin hell is going on.
