Greatful add-on, WORKS ADMIRABLY.

Very simple to use, very handy to have

Compared to lots of downloader, I think it's best youtube video downloader extension of Firefox yet, much simpler than Video DownloadHelper.

If it add new feature like local conversion for 1080p & bookmarklet addon, I will give it five stars and pay for use

This add-on seems to keep up to date on a regular basis even when Youtube seems to change it's mind every week & changes things. Rarely is it inop. The 1 thing that prevents me giving it 5 stars is that at one time the download speeds of the smaller 3gp files use to download As Fast as the regular MP4 downloads. Now they drip through under a 100Kbs but that may have nothing to do with the add-on, I'm not really sure. I just miss the faster downloads we enjoyed before on those smaller files. I would like to see the other 3gp file size [240p] offered as well like some other add-ons offer. All in all, I didn't mind donating money to get the more restrictive downloads of of the MP3 files due to youtoob which changes its mind every week on how it works & what it takes away. Good support - thanks

I struggle hard. Grateful.
However, not everything can be downloaded.

Was using another downloader which unaccountably started creating files unreadable by WMP, VLC, you name it...
Installed this and it worked first time with no fiddling around digging for codecs etc; very impressed so far!

I've used other youtube downloader extensions and this one does seem to earn its #1 rating. This one is self-contained (no other extensions or converter programs necessary) and works as advertised with some nitpicks. The download button does not show up when viewing videos in a playlist. It would also be nice to have an alternative to the download button in the menu bar (in case youtube does another sneaky interface update). The extension's built-in description in the add-on manager is a little messy and could be made to look more professional (as appropriate for such a useful extension). Although there are other downloaders that can work with sites other than youtube, I don't mind this one working well with just youtube.

Se ha convertido en uno de mis favoritos y la vengo usando desde hace tiempo, pero es una lástima que la opción mp3 no sea gratuita

NICE ADD-ON SOME TIME NOT DOWNLOADING

keeps on resetting.... have to activate all the time.

Very handy.

good but should allow all downloads

Thanks!

Works well, with minimum fuss. Download options and sizes are clear. Whenever YouTube breaks the old methods, this extension _very_ quickly finds a new way to make downloading easy. Update: Still working well, despite numerous changes by YouTube, in July 2021 - thank you!
