Fantastic Rated 5 out of 5 stars
It really works well.
The acceleration is very real, I saw the fasted downloads I have ever seen, and I have seen/tried many download managers (most were commercial, and I used them a lot).
I have had problems with Commercial recording/downloading software.
One point is if you are using the FireFox HTTPS Everywhere and or HTTPS Finder addons, you will have stopped downloads, and etc problems.
Disable them for You Tube and this Addon should work well for you.
I want to verify I have no problems for a couple weeks, then I will donate.
If this works for you Donate ! Support people who pride themselves on functional software that works in the constantly changing video environment !
Thanks for this addon folks.
