Youtube videos not playing on Mozilla Firefox, but playing with Google Chrome for 2015-01-09

Posted

Hi Guys, Youtube videos have played fine in the morning, but stopped playing recently on my PC and Laptop at the same time. I have updated Firefox to version 34.0.5 and Adobe Flash player to version 16.0.0.235, but that did not fix the issue. My Google Chrome is still working fine with youtube videos. I have the following extensions on Firefox:

   AddBlock Plus 2.6.6
   Avast on-line security 10.0.2502.149
   Flshblock 1.5.18

Any suggestions or ideas? Thank you. Kind Regards, Vladimir

You have Flashblock 1.5.18 installed on Firefox. Mozilla Firefox does not fully support the HTML5 player for YouTube. Your extension is blocking Flash Player which in turn blocks YouTube videos.
