This comment has a strange behavior in Firefox, which is not surprising but it's probably a bug: When I scrolling to this comment there is no characters outside of the comment box but when i switch back to this page from another tab then the characters are going outside the comment box.

Nice utility. What should I tag it with in my bookmarks though?
