The original Free Extension worked well Then the blocking saying a donation needed and upgrade to continue using. I Sent then a 20 spot sure grlad I did not do the 30. Absolutley nothing The green button not even able to add back to Youtube. Then what I get was a Total downloaded app I do not need that totally does not work it is not an extension. I will be contactin paypal for a refund. This is a rip off.
