I can't play or stream online videos with MKV extesions in Firefox though I can play these videos through Chrome. It says "The media could not be loaded, either because the server or network failed or because the format is not supported." while trying to play the video.
I am Using the latest Firefox for Ubuntu 16.04
In uget, when I click on a link it shows me all the details of that download, and then if I confirm it, the download gets queued.
From the queue if I tap the green start button, the download still doesn't start.
So to start any download I have to force start them manually.
How can I make the downloads start immediately without getting in the queue?
