good

Very well done, light weight, easy to use, and extremely useful

Works perfectly with PEACE and APO. Nice clean bass & no clipping.

Works on all videos.
The panel is slow to open.
Thanks.

Checked c.net for a literal hour not finding what I was looking for with many different quarries to no avail...
Typed one word in the search bar for fire fox extensions, and found this, what I was looking for, with in seconds.
Then created an account for fire fox, verified said account, so I could actually rate this, and give it a good review.
(spent more time creating/activating and reviewing this than I did finding it PLUS! installing it) So long story short? Ty!

works very decent:-)

Exactly what I needed, working on firefox 66.0.3 and only requires a refresh of the youtube page if you already had a video playing at the time of installation. PERFECT!!

Have to disable on some sites like viki.com
This is really annoying.2 years without update. Is this addon abandoned?
Still 5 stars but would be nice if this could be fixed.
