Status: UNCONFIRMED

(Firefox :: File Handling, defect)

Description

[p.willis]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.4) Gecko/2008102920 Firefox/3.0.4
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.4) Gecko/2008102920 Firefox/3.0.4

When saving a page containing text, if the browser window is set so that long text lines are wrapped, the page gets saved containing the additional newline characters.

This is a problem if the browser is displaying a delimited text file with wrapped lines. Essentially the delimited text becomes useless for importing into anything.

Reproducible: Always

Steps to Reproduce:
1. Make a PHP file to serve from HTTP server:
<?php
   echo "THIS IS A SINGLE LINE WITH REPEATING TEXT THIS IS A SINGLE LINE WITH REPEATING TEXT THIS IS A SINGLE LINE WITH REPEATING TEXT THIS IS A SINGLE LINE WITH REPEATING TEXT THIS IS A SINGLE LINE WITH REPEATING TEXT THIS IS A SINGLE LINE WITH REPEATING TEXT THIS IS A SINGLE LINE WITH REPEATING TEXT THIS IS A SINGLE LINE WITH REPEATING TEXT THIS IS A SINGLE LINE WITH REPEATING TEXT THIS IS A SINGLE LINE WITH REPEATING TEXT ";
?>


2.View the page URL with firefox.
3.Move the browser window so that the text wraps in the view
4.[File>Save Page As...] and save the page as a text file (while wrapped on screen)
5. Look at the saved text file with an editor.
6. note the additional newline characters 
Actual Results:  
text is saved containing additional newline characters as viewed in the
browser display window

Expected Results:  
text should only contain the characters sent from the server with no embellishments provided by browser.

I can confirm this is still broken in 3.6.3 on Windows XP. However, this is not limited to just text files: When saving a HTML page with inline javascript (in my case in an onclick attribute), those are wrapped as well. When this inserts a newline inside a string constant, the javascript breaks, making the saved page useless.

This seems to be specific to Windows XP, or at least I couldn't reproduce this on 3.5.6 on Debian Linux. The problem also seems to occur only when saving a complete webpage, not when saving HTML only. It occurs both when the page being viewed is online as well as when it is a local file.

I'm attaching a simple html file containing a javascript alert() in the body onload tag with a long string, showing the problem.
