User-Agent:       Mozilla/5.0 (Macintosh; U; PPC Mac OS X; en) AppleWebKit/419 (KHTML, like Gecko) Safari/419.3
Build Identifier: Both Thunderbird 1.5.x.x and

We right click on an .html  attachment and ask Thunderbird to open the attachment with Firefox.  When Firefox opens the attachment it displays as raw text instead of interpreted HTML and the URL in firefox shows the file name ending with ".html.txt"   If the attachment is instead saved to the desktop by Thunderbird, it gets saved correctly as a .html file and when double clicked, opens firefox and displays correctly as a richly formatted HTML document.

Reproducible: Always

Steps to Reproduce:
1. Right click on any .html attachment in your inbox and choose open
2. Choose to open with Firefox, it opens incorrectly.
3. There is no step 3
Actual Results:  
The document opens as raw, uninterpreted html text and the URL line has the path to the document that ends with ".html.txt"

Expected Results:  
We would expect the .html document to open in a web browser (any web browser, including Firefox) and be interpreted and displayed as HTML not as TXT.
