I have installed/uninstalled it about 6 times but it will not "show" itself on the toolbar with my other add-ons. Here are my issues:
1. IF you have lots of add-ons, this will cause a problem. The ICON here does not match the one that will appear on toolbar. Will be hard to "match", "find" on hi-resolution desktop. Here it is an "down" arrow pointing to a line" but on the toolbar it is not and too small for me to see it.
2. I don't remember the install sequence I used to make it finally install but it was not exactly like others add-ons but finally got it to install and works OK.
The issue of no AUDIO download is not an issue with me as there are lots of "strippers' and converters" as I EDIT my MP3 to remove crap from front and back.

Всё ок. работает. как надо работает не то что другие.

Addon with mining script. use any antivirus too see

Fast and straight forward; easy and intutive

Странно, видео есть в разрешении вплоть до 1080p а выбор только в MP4Normal 360p

Works like it should. :) Love it... :D

Пожалуйста, добавьте скачку mp3! Спасибо! Please add an option to download mp3. Thank you!

Simple and works without fuss. Exactly as it should. Recommended.

один из немногих, что работает с видео с ограниченным доступом
