I don't see why you couldn't. We had trouble getting on the net using our wi-fi, and once we got on it was very slow going. But if you can get on and move around you should be able to watch anything on there
Yes. with the exception of a few websites, you can pretty much watch any streaming content on the chrome browser built in. However, I would suggest getting the Chromemote extension (for The PC version of Chrome) as it allows you to "fling" a page that you are currently viewing on you PC and send it directly to you Co-Star. But be warned, if you have an extension like Adblock or AdBlock Plus installed on your PC it will not install on the Co-Star (at the time of this review) so pop-ups can be really really bad.
This requires either a wwebsitestream or an app. For example the espn app would allow for this but only content they stream live. You may need to "side load" an app to do this. With only a few exceptions, everything I can do on my android tablet or phone, I can do on the co-star, but you may need to side load apps on the co-star that aren't officially supported for the co-star.
It doesn't have actual tabs like Chrome but it does have an icon that you can click to open other windows so you don't lose your pages. It's not as convenient as using a tab but it's better than having to retype everything. Hope this helps.
Did not order--item number was listed incorrectly by company..did not order Vizio co-star stream player..company made me receive item and then shipped back..not helpful at all even tho it was their mistake.
