Bug Description

Firefox 60.0.1 (64-bit), Ubuntu 16.04.4 amd64

Link addresses for IPv6 are tricky. IPv6 address has to be extended with network interface (zone id), to signal OS what network interface to use.

When I try to connect with Firefox to following URL

http://[fe80::87f4:81fa:b481:d781]/test.html

it is confused. It even doesn't report an error that it cannot do that.

When I enter URL with zone information, Firefox returns "search" results, in means, it doesn't understand this syntax of IPv6 address...

http://[fe80::87f4:81fa:b481:d781%enp4s0]/test.html

Here is RFC describing zones, https://tools.ietf.org/html/rfc4007

Demo with CURL, that can handle such URLs without any problem:

user@test:~$ curl http://[fe80::87f4:81fa:b481:d781]/test.html
curl: (7) Couldn't connect to server

user@test:~$ curl http://[fe80::87f4:81fa:b481:d781%enp4s0]/test.html
<html><body>TEST</body></html>

user@test:~$ curl http://[fe80::87f4:81fa:b481:d781%2]/test.html
<html><body>TEST</body></html>

user@test:~$ curl http://[::1]/test.html
<html><body>TEST</body></html>

user@test:~$ curl http://[::1%lo]/test.html
<html><body>TEST</body></html>

The upstream bug report (https://bugzilla.mozilla.org/show_bug.cgi?id=700999) was closed as RESOLVED WONTFIX because they want to follow the proposal for URLs by WhatWG which doesn’t mention link-local IPv6 address specifiers.
