Thumbnail Viewer for YouTube™

Does what it's supposed to, though it shows the picture with the wrong aspect ratio. Not a big deal, you can open the image in a new tab and see it correctly, so I'm not deducting any points, but would be nice if this were fixed.

There is one where you right click the video. For this one, remember to click the extention itself where the puzzle icon is.

It's working perfectly!

Cool It's working

this was so great it allowed me to get jacks, marks, and ssundees thumbnails

it did not work for me perhaps it is outdated or my system is somehow interfering.

good app

Ever since YouTube removed the stop download function from their player I feel my life was incomplete. Now that I have the "Master's Youtube Thumbnail Viewer" in my life, I feel whole once again.
