Support for older browsers

[ffytczuthp]

Hello.

Why does the send.firefox.com website not work in old but still widely used browsers (Firefox 52.9 esr, Chrome 49)? Larger websites and websites with more functionality (e.g. facebook.com, duckduckgo.com, instagram.com) work fine in older browsers, and your small website doesn't work. What features of new browsers that are not in old browsers do your website need?

Could you add support for old browsers for your website, please?

Thanks.
