As in summary, on this page [1] if I use FF 2 I can download everything just fine. On the contrary, in the same page with Firefox 3 beta 5 I can't.
Other people have this error.

Any idea?

I can reproduce the bug on Mac.  I get a "File Not Found" error page (despite it being an http URL) on trunk, and a download dialog in Firefox 2.

We get in both cases a 404 :

Firefox 2 download the 404 page as file while Firefox 3 stops at the http status ocde. This seems to be correct and I think the epage is just broken.

You can very easy see this if you use http://www.aldolat.it/download/index.php?dl_id=3 on http://web-sniffer.net.

and this a change from bug 312727 AFAIK

Comment 7

I do not understand why FF 2 (on Ubuntu or Windows) can download, while FF 3 beta 5 cannot download.

Can you explain me?

Comment 8

[Matthias Versen [:Matti]]

It's already explained here.
The page sends a 404 file not found for the download link.
It also sends the download itself as 404 content of the 404 response, usually used as the error page itself.

Firefox2 downloaded the "error page" while Firefox3 just displays it's internal 404 error page and it doesn't use the submitted content in the 404 response.
This is a valid design change from bug 312727.

The page must send a http/1.1 200 OK

BTW: You also can not download this file because of this error in the page

and if you don't know anything about http status codes you can use http://en.wikipedia.org/wiki/List_of_HTTP_status_codes for a list which includes 404

"BTW: You also can not download this file because of this error in the page"
should be 
"BTW: IE7 also can not download this file because of this error in the page"
