This extension modifies the wrong thumbnail element. Jambo only appears for a split second when hovering over videos, before the preview starts.

it's great! Love it lol. But it doesn't seem to work on the homepage? But it works on channels and when searching for videos, and on the "end of video, new video suggestion" screen thing. But not on the homepage itself. Still, it's so funny haha

it's fookin Jambo, mate. what else could you ask for? who dafaq said perfection doesn't exist?

JAMBO

Because it is Jambo.
THANK YOU FOR THAT!

would've been 5 stars, but unfortunately, sometimes schlatt shows up alongside jambo

If I could have only one extension on Firefox, it would be this.

Very cute, does what it advertises, but it eats CPU :( I have a relatively high end PC and this was pushing it close to 20% CPU usage at times, and now that I've removed it that number dipped by a lot.
