Firefox slow DNS-Lookups

Post by user12 » 18 Jun 2010, 14:56

Hi,

I use systemrescuecd-x86-1.5.6-beta10.iso

Browsing using the included Firefox is very slow as DNS-Lookups are very slow.

After a search on the internet I found out that the reason is a problem with IPv6 even if you don't have or use any IPv6 devices. It takes about 20 seconds for Firefox to resolve the IP from a domain-name.

What helps me is to change in "about_config" :

network.dns.disableIPv6 to TRUE

Source: https://bugs.launchpad.net/ubuntu/+sour ... bug/417757

I do not know what you can do here, just wait for Firefox to resolve this issue?

If it's a firefox bug, I prefer just upgrading firefox when the next version is released.
