it is real good. love it

I have been using this add-on for a few years now. It works great, is updated when needed, and it is easy to use.

one of the best

Only add-on that is working for me at the time - and it works perfect.

For pro features (i.e. 1080p and mp3 audio conversion), sometimes had to try later because they were temporarily not available. But worked again 10 min later.

So sad this seems to not work any more, it served me well for years. I hope it may be fixed in future.

Awesome

This software is one of the main reasons I have stayed with Firefox. Very really Super Useful

good
