Rated 5 out of 5 stars

Works PERFECTLY. Not just plug and play but very easily set-up. Since it is able to save the DASH formats I have given this addon the full five stars. I was using other youtube savers beforehand yet 1080p was always unavailable so I am thankful and have respect for the programmer(s). I am using v5.3.0 and always the newest Firefox.

This review is for a previous version of the add-on (5.2.1.1-signed). 

Much appreciated, thank you. Please try the interim fix (v5.3.0) here:
