Useless Rated 1 out of 5 stars

This thing is horrible and it never works. There are other apps out here that actually do get the job done, this isn't one of them.

it works! Rated 5 out of 5 stars

it does what it has to do. perfect integrated into youtube and download of HD 720p.
Works also with PaleMoon 26.x
It would be a very nice bonus if it could download WEBM... maybe in the the update?
anyway, 5 stars for this clean, simple and well working add-on.

Download Issue Rated 5 out of 5 stars

In response to Xsile's review, I have had the same problem, but it is very rare. I also have 'VideoDownload Helper' installed, and I get the same results with those videos. So I think it is a YouTube problem, and not the extension.

not at all Rated 1 out of 5 stars

Not working for me. It places the download button but when trying to download anything from youtube (regardless of quality choice) download finishes immediately with 0 bytes downloaded.

Manually installed, but... Now no more download button:-( Rated 5 out of 5 stars

Hello developer. Thanks for your mail and the explanations. I did as you said, but now there's no more download button!

I have here installed the newest Firefoy 43.0.3 in both versions (32- and 64 Bit). Same issue with both, no more download button:-(

I wish you a Happy New Year as well!

1.8.5 Only 360p Rated 3 out of 5 stars

Would normally get 5 stars however .. Manually installed 1.8.5 but it only downloads with a resolution of 360p no matter what HD versions are available on Youtube (ie: 480p, 720p).

Edit (as no reply button available) Tried to clear youtube cookies and restart browser. Still no good I am afraid, same result. Using Firefox version 43.0.3.

No longer works with FF latest update Rated 3 out of 5 stars

When I clicked the 720p Download button, it redirected my current YT tab to this.
Please update this extension ASAP..I've been using it pretty well till this FF update.

This review is for a previous version of the add-on (1.8.4). 

Thanks for your bug report. I've uploaded version 1.8.5, which fixes this issue, but it needs to be reviewed by Mozilla first and it should be published soon. Unfortunately, extensions need to be signed by Mozilla, so I can no longer post the URL for you to download the new version. You can still disable signature verification if you use Firefox Dev/Nightly: https://wiki.mozilla.org/Add-ons/Extension_Signing#FAQ and install the latest version from here: https://addons.mozilla.org/en-us/firefox/addon/download-youtube/versions/

Easily a five Rated 5 out of 5 stars

This extension was able to do what Real Downloader and Free Download Manager are no longer able to do. I like how it integrates with the FF's download manager. I also like the fact that this extension doesn't add another button to the toolbar area of the browser.
