For some reason, starting about a couple of days ago, Firefox will NOT load the site vine.co - it displays the "Unable to Connect" page (see linked image) and I can't think of anything to do. All other video players work - on Youtube and Facebook and it's very strange that I'm not able to access only this entire site. Also, on sites such as Twitter and Tumblr, I am not able to access the vine videos (that have been linked, I assume, from vine.co) - it will just show a square on the webpage where the vine video player should be but it just has the "unable to connect" image instead. I have Ubuntu, all updated, and Firefox is updated as well to the best of my knowledge. Does anyone know how to solve this problem?
