I think that this is correct behavior. GitHub doesn't provide Content-Disposition, so we don't have a download name at all - we just have the URL, which could be quite misleading - e.g. this very Bugzilla page has an URL that looks as if it were a "show_bug.cgi" file, but it's actually HTML is one were to download it.

So given that the only thing we actually know about the downloaded file is that it's text/plain, adding .txt to make sure that it opens in a text editor is best.

I would rather have Safari support different file extensions for download like css, js, etc and allow downloading them as such, instead of adding .txt extension.


If a file with extension other than the above gets downloaded with content-type: text/plain, in such cases Safari can add .txt.
