From: faeychild on 26 Feb 2010 01:16 The short story to skip the pain. I was modifying the 'about:config" settings and Firefox refused to start. I have tracked the problem down to network.dns.disableIPv6 in prefs.js If set to true Firefox wont start. If stared from the desktop icon I have to wait for it to time out If started from the command line It reports a segmentation fault. If disableIPv6 is set false, firefox starts OK ideas anyone? -- faeychild Running kde on 2.6.29.6-desktop-3mnb kernel. Mandriva Linux release 2009.1 (Official) for i586

Get newer release :) # grep -i ipv6 ~browser/.mozilla/firefox/*default/prefs.js user_pref("network.dns.disableIPv6", true);

I also set/add user_pref("browser.download.manager.scanWhenDone", false); user_pref("browser.safebrowsing.enabled", false); user_pref("browser.safebrowsing.malware.enabled", false); user_pref("browser.search.update", false); user_pref("geo.enabled", false); user_pref("network.dns.disableIPv6", true); user_pref("network.dns.disablePrefetch", true); user_pref("network.prefetch-next", false); Have you disabled ipv6 on 2009.1. I have used these in the past. echo "install ipv6 /bin/true" >> /etc/modprobe.conf echo "alias net-pf-10 off" >> /etc/modprobe.conf echo NETWORKING_IPV6=no >> /etc/sysconfig/network For 2010.x I use echo "alias ipv6 off" >> /etc/modprobe.conf

It's strange what you imagine you have done only to find out you didn't. Well after all the IPv6 lines were written and IPv6 was disabled on Firefox, the browser started. (surprise) But wouldn't connect :-(. While on the way to check resolv.conf I had a look at hosts. The entire formatting was scrambled "AGAIN". No separate entry of one per line, just a big scrambly block of text. Quite an achievement considering that after the last time it happened I left the file permissions read only. After copying over the bakup file, Firefox runs OK. I can't see how the hosts file would have made any difference to Firefox So thanks Bits.

That was the result from the grep to show you I was using the same keyword and value which are working for me. Your change(s) in about:config get written into prefs.js. > Well after all the IPv6 lines were written and IPv6 was disabled on Firefox, > the browser started.

I use privoxy with http://www.neilvandyke.org/privoxy-rules/ to block ad sites. Using https://www.opendns.com dns servers to help block malware sites. > Quite an achievement considering that after the last time it happened I left > the file permissions read only. Oh yeah, the famous /etc/hosts dinked up by MCC networking gui tool Feature. :( |
