Out of the box? No. No browser and never flash support. Buuuuuut... if you are really jonesin' for that web browser there are a few 'patches' that will install a lot of additional software including Couch Surfer or Firefox. Sadly though these additions require you to jailbreak the AppleTV. While it does not void the warranty in any way, if you are not comfortable with jailbreaking then you are stuck with the stock Apple setup.
