[Bug 1775926] Re: Firefox cannot handle IPv6 addresses well

Fri Jun 8 20:29:30 UTC 2018

** Description changed:

  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 me "search"
+ 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 that such URLs without any problem:
