Great extension, very easy to use, the code is public and you almost collect no data.

The only thing is that the size of the "screenshot" depends on the video size on the screen instead of the resolution. It is good when a video is of low res, then I can still get a large picture without needing to zoom in.

However, if a video is of higher resolution than my screen (more than 1080p), then there's no chance for me to download the full res frame.

Therefore I'd propose to give users a choice between a screenshot (literally, as it is now) or a frame download.

I love it, but it doesn't work if the video is a part of a playlist I have to copy the video URL from the share button and open it again

this works better&easier to take a screenshot on youtube than any other way without the time line showing but for some reason I have to disable then enable again or uninstall reinstall for it to show the screenshot button the screen after turning my laptop off because it don't show on the screen after turning my laptop off
