The clipper doesn't capture any thing. It appears blank.
The 1st attachment shows the screen on Firefox (but the same happens on other browsers).
The 2nd attachment shows the note it creates. Also completely blank, but keeps tags and annotations.
The 3rd attachment shows that this only happens with "youtube" type of capture. It doesn't happen for bookmarks, for instance.
Edit: It was working fine in August, the last time I used. That's I assumed the problem was the new layout of youtube.
