From what I can tell, Netscape Navigator supported HTTP 1.1 from version 2.0 and up AND Navigator version 4.x ran on Windows 3.1. I wonder if there was a problem getting that version to run on their emulator.
There has been no problem - we were just focused on getting the oldest, earliest browsers we can get running. It's not about getting a fully standards compliant browser made 20 minutes ago to run in a browser made 10 minutes ago. It's about providing easy, hopefully pain-free access to web history.
