While using the cast feature on firefox, which is an amazing amazing amazing add to this new version I've noticed there are a couple issues with controlling the video while casting to my roku. The roku remote does stop and pause the video but there is no way to fast forward or rewind. I haven't found any other ways to do this directly from the browser either. Am I missing something , or is this only because it's still in the beta period?

Thank you so much! Kevin Mitchell
