Pretty good, especially with changes to Youtube recently.

This plug-in is the best for downloading videos on Firefox and quite simply works well. Don't bother messing with other alternatives when you have the option of choosing this instead. Save yourself the hassles and get this plug-in. You'll be glad you did!

Very quick, no nagging ads.

Overall a good tool if you want videos of varying quality. If I had money to spare I'd donate and plan to in the future, as they deserve every penny for their work.

Fantastic. you should use it

Works well and easily!

Una gran herramienta que me permite guardar investigaciones personales y videos interesantes!

Does what it needs to do! That's all you can ask for

very nice add-on. thanks for the update!

Love this add on. So easy to use and they are always keeping one step ahead of YouTube. Now when I see a video I like I can get a hard copy for possible future use. Too many times I have gone back and and the video had been removed.

never had a problem with it, its great

This extension has been able to download almost every video have wanted to download. Another feature which is useful to me even fro videos that I just want to watch but not download is that will show the data size of the video - this useful because I access the internet via a metered hot spot plan with a 50 GB/month data limit. I highly recommend this extension.

This is the best add-on that I use with Firefox. YT often changes things so that the add-on does not work at times. But this guy does a great job getting it to work again!

La uso mucho para descargar videos de youtube y para copiar los links y reproducirlos en VLC player, ya que la pagina de youtube en mi laptop me da mucho lag. Gracias por solucionar el error que no permitia descargar
