The only working add-on of such a kind. Pity it is no longer providing 720p, but it is sufficient for my needs - to extract (with a special converting software) audio for talk videos - just to listen. For full HD I can use stand-alone desktop soft.

Have been using this app for occasional higher quality downloads for years. Recently had some difficulty enabling the PRO features, but the developer quickly responded to help me solve the problem.

Great tool, i have bought the Pro Version. BUT: it is still not possible to download YT Videos in 720p
only in 360 or 1080p. Thats a great problem.
First this format is best in quality and size and your addon also always showed me if i already had this Video in my folder and stopped download.
Can you give information about the development of this tool please ?

the pro version works very well

Easy to use, great tool.

I love this plug-in extension add-on. Though it has not work for me as of late. Probably due to Youtube updates against Firefox's own updates. Hopefully the creator of this app can resolve this!!
