Suddenly Firefox-ESR and Iceweasel can not lookup DNS but
/etc/hosts works fine. Other programs does also work fine:
I have gone through http://mzl.la/1xKrMnN Firefox can't load websites but other browsers can, no firewalls prevent Firefox from DNS, IPv6 disabled, no proxy and no DNS prefetching.
$ egrep "network.dns.dis|proxy" ~/.mozilla/firefox/*.default/prefs.js user_pref("network.dns.disableIPv6", true); user_pref("network.dns.disablePrefetch", true); user_pref("network.proxy.type", 0);
I have tried
purge & install. Login as a new defined user does not work either. Then:
mkdir debug ; cd debug strace -o f -ff firefox http://example.org/ grep -rn example.org f*
and to have something to compare with
strace -o k -ff konqueror http://example.org/ grep -rn example.org k*
I have gone through the files but have not found any smoking gun yet. Where to go from now? Reinstall the computer?
