This TRASH just blocking from loading "suggested" videos column... /-:

takes a few seconds before it starts to load, meaning its quicker to click a video. cant mute it.

Cool

Still Works on latest Firefox 2018

the add-on doesn't work in the new youtube design.

Seems working on the latest Nightly. Thanks!

This addon only works in the old Youtube Theme. If you are using the new Theme, which is now standard, it doesn't work at all.

Great idea, works well except for a few userstyles that cover the thumbnails up on hover. Also the addon doesn't seem to respect the settings you give it.

This is the only addon I found that actually works!
