I am new to Ubuntu and I have installed 14.04. When I went to YouTube via Firefox it informed me that there was a YouTube app and asked if I wanted to install it. I said yes, and it installs. When I try to play videos the app acts as though it is going to open them, but the loading icon pops up and the video never seems to start playing. If I go to the video in Firefox, the videos do play but I was hoping to use the app to watch the videos and have full access to my account. Does anyone have any ideas on how to make this work?
