good

Cannot detect file.

After a few years of using stream-grabbers, I never found one as simple and powerful as downloadhelper. This is the best thus far! Krishna Das.

Works perfect on non youtube videos too. It can name automatically according to the sequence. But hated the watermark.

Стабильно и очень быстро

This add-on works awesome! It helped me keep copies of some old videos that I had lost.

simple in use, great in results

OLD version was function well

New version downloader update last week was poor performance, lousy, many problems+
Downloading slow
Downloading stop half way
After download, video format not compete, error

ab und zu brauch das pogramm zu lange

The app is so easy to use

No ”Video DownloadHelper” , No "Firefox"

Leidert nicht verwendbart. Es will nur installiert werden, wenn FX zuvor installiert wird: und das, obwohl FX iunstalliert ist! Also unbrauchbar.

Very Good
