Does not work on high resolution videos. 144p and 240p will download but for hi-res videos need an "ultimate" version of the software which you have to pay for and install separately.

super

Does not work with new Youtube!

It detects videos but won't the download button does nothing. I'm not installing the extra add-on in the hope that fixes it.

so far its been reliable

wouldn't let me download until I downloaded another thing, yet another addon that tricks you

use this, work all fine for me up to now, do not use the Video DownloadHelper which asks you to install extra(?) app.

better App :) recommended

Very good
