992497 - "Save Page As" should use filename extensions ".html" and ".xhtml", not ".htm" and ".xht"

Status: UNCONFIRMED

(Firefox :: File Handling, defect)

Description

[Andrew Church]

Firefox 28.0 (and SeaMonkey 2.25) offer the default extensions ".htm" and ".xht" when saving an HTML or XHTML page, respectively.  At least on Linux, there is no reason to enforce 3-character filename extensions; the default extensions should be changed to ".html" and ".xhtml".

Steps to reproduce:
1. Open any HTML page in the browser (such as http://www.mozilla.org/).
2. Select "Save Page As..." from the File menu.

Expected behavior:
The default filename in the Save As dialog should end in ".html".

Observed behavior:
The default filename in the Save As dialog ends in ".htm".

Using Fedora 18, I visited mozilla.org, chose Save Page As and saw '.html' in the dialog. Could you give more information about your environment?

Interesting; perhaps it's an OS configuration issue.  I'm using Gentoo Linux, amd64 base profile, and to my knowledge I haven't touched anything related to default extensions.  Does the save-as dialog ask the OS for the filename extension, and if so, do you know where it gets the extension from?
