This is a great add-on... !!!!
However, the latest version 0.85 appears to have a slight problem...The "detect-download arrow" appears to fall on the Youtube bar below the video that shows the ---date and the Like or dislike hand---...right between the --- SAVE and SHARE --- buttons of Youtube ........ Maybe there's a CSS adjustment you need to make or a script if you're using one to adjust its position
Thanks anyway...
