I've just installed Lubuntu 14.04.1 and when I tried to go to youtube I coudldn't read a video.
I am using the firefox which is automatically installed when installing lubuntu , the shockwave flash 11.2.202.411 plugin is installed.
I have installed pepperflashplugin-nonfree nothing changed.
Here a screen of what I see when trying to read a video. https://i.stack.imgur.com/gsyS9.jpg There is nothing, no play button, nothing telling me it can't read.
However I just noticed it works fine when using the html5 option https://www.youtube.com/html5/
Is there a problem with flash ? How can I fixed it ?
