@firuz-u7 You're right, it does work! But I had to use my mobile browser, mega.nz isn't working on my PC. I assume one of my browser extensions is interfering - the irony! 😅
Adobe Flash Player (which this Extension attempts to download from Adobe) is no longer available as of 31 Dec 2020. You'll have to find another player, try Ruffle Emulator or find an old computer that you can download the Adobe Player off of.
