it do be working though! Indubitably

great extension!! works perfectly

Works with current YouTube design and with multiple active content blockers. Also saves images in PNG, for the best quality

Very good, and unlike some add-on it won't ask for too much permission, only YouTube domain.
Thanks to the Dev, I hope you're not shady.

A very useful utility that works great! No hassle, simply awesome!

Just works, very good.
