Browser add on does not work anymore. It used to be great and I was one of those who paid for the pro version which also no longer works. I realize the breakage is not Dishita's fault, its youtube security changes nevertheless he still has this webpage up asking for donations for a browser app that no longer works. Yes he says that now he has a downloadable app that works but you must pay before trying it and who knows how long before youtube fixes the security holes he's exploiting. The webpage should be changed to indicate that the browser addon no longer works and as for the app, he should state that you purchase it at your own risk. Youtube could change security tomorrow and render your app unusable.
