List of browsers supported by Wolfram Cloud

Hi,

Wolfram Cloud doesn’t seem to support many browsers currently in use.
For example, I have issues with filling web-forms (FormFunction[]) when using Internet Explorer 9,0.
I wonder if Wolfram Research keeps a list of supported browsers, so I could check if my client uses an unsupported browser and recommend to use a better supported one. Also, is there a *proffered" browser to use WolframCloud aps?

Thanks in advance,
Stas

We support the latest versions of Chrome and Firefox. I would recommend using the latest version of Internet Explorer (11) as well.
Chrome usually gives the best performance.

John, does this include the browser in a chromebook?
