So I cleared cookies in Page Info>Security and cache in Options>Advanced>Network, I don't know if that helped but now I am able to download playlists in Ummy again with no issues, I wish I could edit or delete my post and profile from this website, even though the extension still doesn't work 100% right now, I'm going to use Ummy in it's place.

Uninstalling and reinstalling the extension to Version 6.20 of SaveFrom.net Helper did not produce a fix to this bug, also cannot download links in Ummy Video Downloader.1,7.2.2 either.
