Instant video previews in popup player by hovering or clicking video thumbs. Video ratings and resolution data no longer shown on the thumbs. This is a fork of Costas' original with Arantius' GM4-Polyfill js.

Correct - YT no longer displays likes/dislikes until you click on a video. I will modify and rename this script.
Ratings not working March 2020
When I installed this in March 2020, I found the ratings display does not work and it's not possible to disable options using the control box. I understand that there were changes made by Youtube in February 2020 that have broken a number of third-party scripts so this script probably suffered along with them.
