1079721 - IPv6 URLs are not considered search strings despite having "network.dns.disableIPv6" set to true

Status: RESOLVED INVALID

(Firefox :: Address Bar, defect)

Description

[Andrei Vaida [:avaida]]

Note: this is a follow up bug for Bug 494092.

Reproducible all the way back to Firefox 4.0, across platforms.

STR:
1. Launch Firefox with a clean profile.
2. Access about:config and set the following pref to true: network.dns.disableIPv6
3. Restart the browser to make sure the change is applied.
4. Type in the following IPv6 URL: http://[FE80::0202:B3FF:FE1E:8329]/

ER:
Since Bug 494092 landed and with 'network.dns.disableIPv6' set to true, any IPv6 URL should be considered a search string and a <default_engine> search should be performed for it.

AR:
Despite having 'network.dns.disableIPv6' set to true, Firefox is treating IPv6 URLs as URLs and attempts to access them.

Additional notes:
- This issue *is not a regression*.
- This issue is reproducible across platforms.
- See Bug 494092 Comment 36 for context, I believe it's reasonable to consider this bug a potential enhancement.

"network.dns.disableIPv6"
Did you notice the "dns" part of the pref ?
Setting this pref to true disables only the DNS resolution of names to IPv6 addresses.
(example: mozilla.org -> [2620:101:8008:5::2:1] )
IPv6 URLs can be still accessed and that is what i would expect.

There is no pref to disable IPv6 completely in Firefox/Gecko but that is what you are looking for.
