User reviews

This is the most useful extension I have. Without it, I would get so annoyed, trying to remember what I have and haven't watched. I know there are others out there, but this one does exactly what I want it to.

This extension has been so useful to me over the years, I am begging you not to let it get shut down due to technicalities 🙏. I'm literally considering learning JS just to help solve the whatever issue is making chrome block it
