No HTML Interpretor?

I have a mac using the latest version of Komodo IDE and I can’t run HTML files because there is not HTML interpreter. I have no idea what that means or how to get one. Can anyone help?

It sounds like you are trying to debug a HTML file. Are you trying to use the remote browser debugging? If so, check out

If you are simply trying to preview HTML files check out
