Dear Sir or Madam,

A few days ago, I suddenly started getting this error message when I try to open
any .swf :

The file “sbemail1.swf” is of type application/octet-stream (Shockwave Flash),
and Mozilla does not know how to handle this file type.  This file is located
at: http//www.homestarrunner.com/

I searched your site for answers, tried reinstalling Mozilla, tried reinstalling
shockwave.  Nothing works anymore.  Why did all the .swf's suddenly stop
working?  The website is fine.

Reproducible: Always

Steps to Reproduce:
1.Go to http://www.homestarrunner.com/sbemail1.swf
2.Go to http://www.homestarrunner.com/sbemail20.swf
3.Go to http://www.homestarrunner.com/sbemail23.swf or any other.

Actual Results:  
The file “sbemail1.swf” is of type application/octet-stream (Shockwave Flash),
and Mozilla does not know how to handle this file type.  This file is located
at: http//www.homestarrunner.com/

Expected Results:  
open the .swf and play it.

Are you sure your server is working correctly? The SWFs will probably
work if sent with the usual mime type.

I´m seeing the same on http://www.homestarrunner.com/sbemail1.swf
I got asked what to do, then canceled, opened about:plugins to see if flash is
seen. Flash was installed:

    File name: C:\Programme\Opera\Program\Plugins\NPSWF32.dll
    Shockwave Flash 7.0 r19

I also know that it was found, as I used the nightly before.
In Bug 281509 comment 2 I´ve seen a flash loading in a frame, but I couldn´t
load it directly from the URL, download was offered ( URLs in that comment)
 

Bug 277921 Clicking a plugin file link downloads it instead of loading inline.
Bug 273785 plugins not scanned/detected on startup (empty plug-ins dialog in
downloads, open-with dialog for PDFs)
