I've been using this add on for many years and I absolutely agree that this is the "Best Youtube Video Downloader".
That said I asked myself if it was worth supporting all the constant work, effort and expense that Dishita incurs to keep current with all the code changes between Youtube, Firefox and all.
My answer was YES IT IS and I went Pro sending an easy payment via PayPal.
How about you?
Thank You for this add on Dishita!
