Didn't seem to work at the beginning but later in the week I realized it started working. Kind of miss the ClickBait thumbnails and forces me to read the description but it's easy to shut off with "Extension manager" if need be Only wish there was a version that would work on all videos / platforms.
better if it works on home page.
works great! Just what I needed. Thanks!
