ÇOĞU ZAMAN GÖREVİNİ YAPMIYOR

Do not work: "Batch downloading is interrupted."

Excellent accessories! Thank you for its development.

Stopped working for me. Again. No more button. Very slow download of all streams and stops unexpectedly.

Works! I have a mac and use firefox, and at the time of writing this, the extension does what says it'll do. The icon appeared, I asked it to download a video off youtube, it did, job done.

Extremely complicated installation. I followed the first step in the "About this extension" section, install "native client" (whatever that is) - nothing. I don't really need or want HD - my connection has a data limit - but I decided to try installing the ffmpeg thing too. It hasn't helped. The icon below the video produces a big orange box with only an hourglass in it. "Quick download" (upper right corner of the browser screen) produces a "Please Wait" message but the browser shows no download in progress and if there is one, I have no idea where it's been saved (I looked in all the usual places). The Settings page includes something about an "ffmpeg path" with a box that's empty; maybe it's supposed to have something in it but I don't know what. I don't understand most of what's on that Settings page anyway. This extension may be fine for people with a lot of knowledge of how addons work but that doesn't include me and I'm stumped. From my point of view, basically - it doesn't download anything and I don't know what to do to make it start. I'm removing it.

By default, is not working for audio-only, downloaded files not working ... need more steps !
