If a YouTube video does not start playing
You may face this problem sometimes, when you press the play button of a YouTube video, and nothing happens.
If you press the pause button, trying to restart your video, again nothing happens! The only solution seems to be a refresh of the whole web page, then to try again playback.
There is a faster solution, though. Right click on the video and select the “Stop download” option. The play button will appear again and you can try if this time playback works as usually. If not, right click again, select “Stop download”, and again press the play button.
Repeat the same process as many times as you need to overcome a problematic connection and at last see your video, without refreshing the whole page.
