<h2>How can to fix it?</h2>
I don't know if the solution I came up with will work for you too. My current operating system is Windows 7 with the latest version of firefox browser. 

When I try to refresh the browser, nothing happens. So I restart it and result was the same not working! So I try it (dtube.video) to play with google chrome and there it play so smooth. 

So I came up with my final crazy solution, restart the whole PC and try it again on firefox. Now it works so smooth, and buffer faster than the one on google chrome. It's not so complex solution but it will help.

<b>See how it works well with firefox after restart!</b>
