1336858 - New Tab Top Sites doesn't distinguish between multiple sites on same server

Status: UNCONFIRMED

(Firefox :: New Tab Page, defect, P5)

Description

[kevin]

User Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:51.0) Gecko/20100101 Firefox/51.0
Build ID: 20170125094131

Steps to reproduce:

Go to two different sites at the same address that use different port numbers frequently enough to show up on Top Sites on the New Tab page. For example: 
http://localhost:8000
http://localhost:8080



Actual results:

Only one of these will show up on New Tab. Each time you use a different one, it replaces the other.


Expected results:

The two different sites should have shown up separately in the list, even though they are at the same server address. Sites need to be tracked down to the port number.

This is intentional, as we dedup Top Sites across domains to avoid duplication.

I am not surprised that it's intentional. However, you are not avoiding duplication with this. I am not talking about multiple pages on the same server, I am talking about different hosts. Even if the domain name is the same, different port numbers usually mean entirely different websites. I have several cases of this and have to use an extension to get a working top sites page. Top Sites should mean Top Sites not Top Domains. Imagine if www.google.com and mail.google.com were treated as the same site. (Maybe they are.)
