Everything works well so far with this extension but, I immediately noticed a strange bug.

On the YouTube Homepage, the thumbnails of each video that shows, have become invisible. I say "invisible" because, if I hover over the video, for a brief second, the thumbnail appears but quickly disappears??

I also found out that, it's this extension itself that is causing this. When I disable the extension, everything goes back to normal, the thumbnails appear and don't disappear anymore. But, as soon as I re enable the extension, the same bug occurs.

Please reply back to this review as soon as you can please and let me know what could be happening here, I'd appreciate it!
