When you right click on a link to a batch file and click save as, it will allow you to save it, but it automatically adds .txt to the end of the filename without informing you.

You are unable to save it as <file>.bat

I see something similar (saved as bat.htm).
This worked fine in Firefox 2.0x but not anymore when Firefox 3.0 came out.

Users downloading .bat files from my site are still having problems with this...

In case you didn't understanding, try the following...

1. Visit http://hm2k.googlecode.com/svn/trunk/code/batch/
2. Right click on any of the files in that directory, and click save link as...
3. Choose where to save it, and press the "Save" button.
4. The file is saved as "file.bat.txt" instead of "file.bat" as expected.

Testet Firefox 3.5.5 and Firefox 3.6 on XP and Win7 and i get the same renaming "problem" as described. 

I tried to download .reg files and not .bat files and the downloaded file was renamed to .reg.txt.

I discovered a work around.

If you add a  asc(7) character in your batch file, it tricks firefox into thinking it is a binary and treats it as such.

This means it doesn't change the file extension to .bat.txt and instead saves it as is.

If you have server access and the server software supports .htaccess files the following seems to work inside a .htaccess file 

<FilesMatch "\.bat$">
    Header unset Content-Type
    Header unset Content-Disposition
    Header set Content-Disposition attachment
    Header set Content-Type application/octet-stream
    Header add Content-Type application/force-download
    Header add Content-Type application/download
    Header unset Content-Transfer-Encoding
    Header set Content-Transfer-Encoding binary
</FilesMatch>

This forces Firefox to recognize .bat files as binary applications preventing it from adding .txt behind the downloaded file.

Firefox, 50.0a1, Build ID  20160616030228
User Agent  Mozilla/5.0 (Windows NT 5.1; rv:50.0) Gecko/20100101 Firefox/50.0

I have tested this issue on the latest Firefox (47) release and latest Nightly (50.0a1) build and is no longer reproducible. For testing I have used http://www.dostips.com/DtCodeBatchFiles.php, the batch files are successfully downloaded with the ".bat" extension.  

Is this still reproducible on your end ? If yes, can you please retest this using latest Firefox release and latest Nightly build (https://nightly.mozilla.org/) and report back the results ? When doing this, please use a new clean Firefox profile, maybe even safe mode, to eliminate custom settings as a possible cause (https://goo.gl/PNe90E).

Considering the fact that I cannot reproduce this and the fact that the reporter did not answered to my request until now, I will mark this as Resolved-Worksforme.

If anyone can still reproduce it, feel free to reopen the issue and provide more information.
