Open file:// url scheme with default handler on Chrome or Firefox

Is there a way to have a link, such as <a href="file:///hello.txt">Click<a>, open with the default handler when clicked from a web browser? I want to let the system take care of opening the file:// URL. Chrome seems to do this for every single URL scheme protocol EXCEPT for http(s) and file.

I don’t mind if I need an extension to do this, but I don’t want to mess with the actual configuration of the host system. Chrome and Firefox just seem very intent on opening the scheme inside the browser — I want to force it to open with the system handler.
