887672 - firefox 22 prefers ipv4 , not ipv6

Status: RESOLVED INVALID

(Firefox :: Untriaged, defect)

Description

[promeneur]

User Agent: Mozilla/5.0 (X11; Linux i686; rv:22.0) Gecko/20100101 Firefox/22.0 (Beta/Release)
Build ID: 20130618035212

Steps to reproduce:

mandriva 2010.2 i586
kde 4.8.4
i use a proxy "privoxy" 3.0.19

privoxy is set to use ipv4 and ipv6 . it reveices connection at 127.0.0.1 (ipv4)and ::1 (ipv6)




Actual results:

till firefox 21 no problem : firefox by default uses ::1 and accesses to sites with ipv6

the proof is that "ipv fox" addon indicates ipv6 is used

with firefox 22 "ipv fox" addon indicates ipv4 is used. more accurately firefox 22 uses
127.0.00.1 (ipv4) to connect to privoxy


Expected results:

firefox 22 uses ::1 to connect to privoxy

Firefox uses by default "system proxy settings"

same pb with "manual proxy settings"

What is your manual proxy settings?

http : localhost 8118

no proxy : localhost,127.0.0.1,::1

in /etc/hosts
there are these statements :
***********************************************************
# generated by drakconnect
127.0.0.1 localhost.localdomain localhost
# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts
*************************************************

i changed

::1 ip6-localhost ip6-loopback

to

::1 ip6-localhost ip6-loopback localhost.localdomain localhost

then

i don't know if i corect , consistant for a good implementation of ipv6
but
there is no more pb

the mandriva network manager restores the file /etc/hosts
then
my workaround disappears !

résumé :
1. the os
Mandriva 2010.2 i586
kde 4.8.4

network is an ipv4-ipv6 hybrid one

privoxy is set to use ipv4 if the app uses http://127.0.0.1:8118 to connect
privoxy is set to use ipv6 if the app uses http://[::1]:8118
to connect

http_proxy = http://localhost:8118

1. firefox 21
1.1. firefox uses system proxy settings

firefox uses http://[::1]:8118 to connect to privoxy

2. firefox 22
2.1. firefox uses system proxy settings

firefox uses http://127.0.0.1:8118 to connect to privoxy

2.2 firefox uses direct connection to internet

- for a site as www.lemonde.fr , a only ipv4 site

firefox uses ipv4

- for a site as www.google.com

firefox uses ipv6

3. I know this :

with previous version with some environments firefox does not use proxy even if there is a system proxy settings.

firefox 22 introduces a new way to take account of a system proxy settings

perhaps this new way has a partial pb with ipv6.
 


firefox 22 introduces a new way to use proxy

i have also the pb with chromium
then
this is not a firefox pb

i assume this is a pb of the so-called ipv4-ipv6 hybrid feature

i set
- http_proxy to http://ip6-localhost:8118
- no_proxy to ip6-locahost,[::1]:8118
