https://github.com/browserhtml/browser.html works fine as a basic chrome too.

Could you expand on "form input fields are rudimentary"? (I know they are, I'm wondering what part of this you're referring to). Is it the styling, lack of selection support, lack of HTML5 input fields, bugs, or something else? (I might be looking into improving these later)

The "go back" crash is something that can be fixed easily; I think we know why it happens but haven't fixed it yet (I forgot the reason though).
