URIs with zone index unsupported

[chrysn]

IPv6 link-local addresses can require a zone index that usually indicates the local link the address is valid on; an example would be coap://[fe80::12:34ff:fe56:78ab%tap0]/. With Firefox 45.2.0, entering such an address results in a "The address wasn't understood" error message, and the address bar gets trimmed to a single :.

The behavior can easily be tested on Linux with a local server if you have any fe80: address on a local interface by appending the interface's name to the address; other operating systems could use different zone identifiers.
