i mean..i guess it does what it says it does but it just functions poorly. it reloaded all the youtube tabs i had at once and i had to hunt each of them down to stop them from playing.....why would anyone want it to work like this?

This add-on only works for me with another add-on, "YouTube Audio" by Animesh Kundu. Basically, it will replay audio-only if you have that add-on, but it will not replay videos. This add-on has not been updated in a few years.
