Can't open an html file on firefox?

[Jill]

Hi, so I downloaded a zip file containing various html files, text files, java files, etc. The place I downloaded it from asks me to open the html file on firefox ONLY. But every time I click the html file to open it, it opens on chrome unsuccessfully. How do I force firefox to open it? Every time I click on the file, Chrome, which is not compatible to the file, opens it voluntarily.

Right click on file, then open with....Then navigate to the firefox app located in c drive/programs/mozila
