Here's a guess:  Maybe the server is badly configured and sending any
"*.bz2" file with a "application/x-tar" MIME.  When you choose to save
this file from Firefox, it tries to be smart and useful (which is the
Right Thing) and suggest to add the "*.tar" postfix (the postfix
associated with the "application/x-tar" MIME type).

To find out, try running the following from a terminal:
        wget --save-headers "http://server/path/file.bz2"
(Change "http://server/path/file.bz2" to the real URL, of course.)

After that, check the MIME that the server sends to you by running:
        grep -a -i '^Content-Type' file.bz2
and see what it tells you.  If my guess is correct, it should give you
something like "Content-Type: application/x-tar".

As usual, I hope this helps.
