boatman9 Posted June 3, 2009 Report Share Posted June 3, 2009 Firefox has become slow to load pages from sites which have third party links, such as ebay. Firefox seems to stall while loading extra items commonly found on ebay pages, such as things from google analytics and pn1.adserver.yahoo.com. I am using Firefox 3.0.10 and recently did a full package update. The problem may have started immediately after the update, I'm not sure. Anyone else have this problem?

scarecrow Posted June 3, 2009 Report Share Posted June 3, 2009 (edited) Is the kernel ipv6 module disabled? To find out, #lsmod | grep net-pf-10 Or also #lsmod | grep ipv6 (net-pf-10 is just an alias to the ipv6 module). Also, if you are connecting via DHCP, then you're likely using your ISP's DNS servers, which may not resolve some IP's very fast. A good idea (most of the times, anyway) is switching to the OpenDNS servers, which are very fast and do not bloack any IP's by default. You must add these lines at the top of your /etc/resolv.conf configuration file: nameserver 208.67.222.222 nameserver 208.67.220.220 and then restart the network daemon ( # service network restart ) Edited June 3, 2009 by scarecrow Quote Link to comment Share on other sites More sharing options...
boatman9 Posted June 3, 2009 Author Report Share Posted June 3, 2009 The same problem occurs when using Seamonkey browser, therefore I believe the problem is not within the browser. Test results: # lsmod | grep ipv6 ipv6 251300 20 I already use openDNS, thanks for the tip. Quote Link to comment Share on other sites More sharing options...
ianw1974 Posted June 3, 2009 Report Share Posted June 3, 2009 Exactly, ipv6 is loaded and so it is the cause of your problem. Within Firefox, you can go to about:config and then filter by IPV6 and disable it. You can also do it system wide by adding: alias net-pf-10 off to /etc/modprobe.conf or by checking /etc/sysconfig/network for ipv6 being enabled and set it to no. Then you'll be fine.

SilverSurfer60 Posted June 3, 2009 Report Share Posted June 3, 2009 A nice add-on is 'noscript' It takes a while to sort out what to allow and what not to allow, but sure speeds up page loading. It stops google-analytics and things like that. At first you will find that a lot of sites will complain that flash is not loaded and stuff but you just allow the stuff you want with a couple of clicks. It works in Firefox but I don't know about Seamonkey. Quote Link to comment Share on other sites More sharing options...
boatman9 Posted June 3, 2009 Author Report Share Posted June 3, 2009 (edited) /etc/sysconfig/network is merely one line: NETWORKING=yes /etc/modprobe.conf contains the following lines. install scsi_hostadapter /sbin/modprobe ata_piix; /sbin/modprobe ahci; /bin/true install usb-interface /sbin/modprobe ehci_hcd; /sbin/modprobe ohci_hcd; /bin/true options snd-ac97-codec power_save=1 alias eth1 orinoco_cs install ipv6 /bin/true Should I delete the last line or change it to "install ipv6 /bin/false" ?

scarecrow Posted June 3, 2009 Report Share Posted June 3, 2009 (edited) No - just delete or comment ( # at the start of the line) the last line, and add right after it alias net-pf-10 off As Ian suggested. Now- to unload the ipv6 module you must first stop the network daemon and then "modprobe -r ipv6", or windows-style, reboot... As for a probable different behaviour of Seamonkey and Firefox, I think (not sure) that in Mandriva both are using xulrunner 1.9.X, so their behaviour should be more or less the same.

boatman9 Posted June 3, 2009 Author Report Share Posted June 3, 2009 (edited) The ipv6 setting in Firefox was already off. I set /etc/modprobe.conf to be: install scsi_hostadapter /sbin/modprobe ata_piix; /sbin/modprobe ahci; /bin/true install usb-interface /sbin/modprobe ehci_hcd; /sbin/modprobe ohci_hcd; /bin/true options snd-ac97-codec power_save=1 alias eth1 orinoco_cs # install ipv6 /bin/true alias net-pf-10 off and rebooted, but problem persists. Maybe it's time to install the most recent Mandriva. Edited June 3, 2009 by boatman9 Quote Link to comment Share on other sites More sharing options...

Greg2 Posted June 3, 2009 Report Share Posted June 3, 2009 Should I delete the last line or change it to "install ipv6 /bin/false" ? If you're using Mandriva 2009.1, you can disable ipv6 with the gui. If you experience sluggish response on the Internet - especially when browsing web sites - and cannot find the cause, you should try disabling IPv6. To do this, left-click the net_applet icon in the system tray this will open the Network Center, now open Advanced Settings and check Disable IPv6, then click OK and restart the system. (You can also reach the Network Center by opening the Mandriva Control Center > Network & Internet > Network Center).From here: 2009.1_Errata#Slow_or_no_internet_response Disabling the ipv6 option will now give you this line in /etc/modprobe.conf [greg@halfway ~]$ cat /etc/modprobe.conf | grep -i ipv6 options ipv6 disable=1 Quote Link to comment Share on other sites More sharing options...
boatman9 Posted June 5, 2009 Author Report Share Posted June 5, 2009 Disabling ipv6 may have improved speed a bit, but the real problem was something gone wrong with flash player. After installing flash-player-plugin Firefox is back to normal and flash is working too. Quote Link to comment Share on other sites More sharing options...
