NetPositive
NetPositive (often called Net+) is the default web browser for the discontinued Be Operating System (BeOS). It includes partial support for JavaScript, but no CSS support.[1] It was originally developed as a stop-gap measure because no browsers had been ported to BeOS.[2]

Error messages in Haiku
    
The browser's haiku error messages were noted among BeOS users, which led to the name of Haiku, an open-source operating system inspired by BeOS. A late 1990s email joke which claimed that Microsoft was moving to Haiku error messages in Japanese versions of Windows was almost entirely made up of NetPositive error messages. For instance, a user might see the following error message if they try to access a website that is unavailable:
Cables have been cut
Southwest of Northeast somewhere
We are not amused.
If the user tried unsuccessfully to authenticate against a website, they might see:
Server's poor response
Not quick enough for browser.
Timed out, plum blossom.
